Some little translation help/grammar help needed

[HaiiroNoAnemon]

Hello, I'm new here and glad that I found this forum, this seems to be quite a good place to learn Japanese, ask questions and talk about Japan
I have some sentences that I have like half translated, but where I can not be sure because I'm not sure about some grammatical thing in them...>///< so it would be good if someone could give me advice concerning those sentence.

This text is very personal and important to me >///<

1)何を見て笑えばいいの？
The -ba ii no form is quite unclear for me what it really means, I know just the normal -ba form of verbs, but -ba ii no? I have read it can be "should do something" or that -ba ii no ni has something to do with wishing something...I have read many possibilities and am very confused about this >///<

also this sentence is even more confusing with mite in the -te form before the waraeba ii no... I thought when waraeba ii no shall mean "should I laugh", I find this sentence strange...What should I laugh to see? It would make sense if it was the other way round "What should I see to laugh?"...but like this...I have no clue

2) the little word まま, it is used often in sentences, sometimes translated (but always different) and sometimes untranslated, so what does it mean? Does it really depend on the sentences what it means?

3) then -達 like in bokutachi, watashitachi etc. I read sentences where a normal word is attached with -tachi, like ko-tachi, or yakusoku-tachi...how can we translate this? We-kids, We-promise...Our promise?

and my dictionary shows me that ko(domo)-tachi is only used in Kansai dialect, is this true? or do Kanto people for example also use it accidentally?

The full sentence conserning yakusoku-tachi would be: 果たせなかった約束達が, 引き寄せ合って, 擦れ違ってく...

...so "our not fullfilled promise", can I translate this like this?
Also I'm confused about 引き寄せ合って, because 引き寄せる means attracting and 合って like suit(it suits?)?

4) What is a good translation for "途中"? middle of the way? on the way? If we say 今は旅の途中。 It is the middle of the way from the journey now. or I'm on the way of the journey?

5) Then the little word "だって" when it stands at the end of a sentence what meaning does it have?

(例えば其れが 過去の自分を否定する事だって。 For example, it's a thing that my past self denies... but it's not complete, the datte is missing and maybe it goes somehow together with koto or sore ga? that sentence is hell difficult for me >///<)

6) 明日を歌うの
Why is there a particle o after Ashita/Asu...wouldn't it be correct/like I know, Ashita (ni) (uta o) utau? How can I translate it if the o is after Ashita?

7) 風口ずさむ
Can I translate this: The wind hums? Shouldn't there be a wa/ga after kaze?

8) 消せやしないから, "またいつか。" って , ずっと笑ってて。
Can I translate this: Because I won't (ever) erase, I said, "See you someday", continuously laughing?

the 笑ってて is concerning me here as well...why -ttete? I only know the grammatical -te form and the -tte form for quoting...

9) いつもそうやって逃げてできたんだよ。
Can I translate this: "I could always escape that way/like this/ doing it so/doing it like this" ?

10) 目覚してよ。
Wake up! or "I'm waking up" or can it mean both? (The text goes further: Wake up!/I'm waking up. Can you hear it? My voice is a friendly memory.)

11) 行き交う人波に, 少しだけ疲れました。
Why is there the particle ni? What does it mean in this context?
With (?) the coming and going crowd, I got a little bit tired.??? (but with is normally to...)
or just the crowd is coming and going, I got a little bit tired.

Thank you so so so so much for every answer beforehand, if you can just answer me one it's more than good as well Because I asked everything of my text I didn't know and that is much x'DD

1)
～ばいい means "Should I~?" in a question. In that sentence, the speaker is asking what she should see (since 何 is the object of 見る), thus, the latter interpretation "What should I see to laugh?" is correct.

2)
まま【儘】の英語・英訳 - 和英辞書 - goo辞書

3)
It's just a personification. 約束達 is a plural form.

my dictionary shows me that ko(domo)-tachi is only used in Kansai dialect, is this true?

No.

Also I'm confused about 引き寄せ合って, because 引き寄せる means attracting and 合って like suit(it suits?)?

The second compound verb ～合う means "(with) each other".

4)
The latter.

5)
What is the sentence preceding/following it? It most likely means "even".

6)
Because it means "to sing about tomorrow", not "to sing in tomorrow".

7)
What is the context/whole sentence?

8)
笑ってて is an abbreviation/a colloquial form of 笑っていて. It's a request. "またいつか。" is not the speaker's words. It's also a request for the addressee. "またいつか。" っていうように makes sense, maybe?

9)
逃げてできたんだよ is possible only in a not-so-common context. Isn't it a typo of 逃げてきたんだよ, perhaps?

10)
Similar to #9 . Isn't it 自覚してよ?

11)
に indicates the target that made the speaker tired.

Thank you so so so so so much for answering *^____^* You already helped me a lot :3
So if it's a plural form I can translate it as "promises" or how can I incorporate the -tachi good/meaningful in an english translation?

(And good cause the person who wrote it lives in Tokyo but I don't know where he originally comes from, so as I saw this, I thought maybe...but it sounded weird to me in the beginning that its just used in a specific dialect ^^')

The sentence with -datte is "例えば其れが 過去の自分を否定する事だって。"
Here I'm also confused with the sore ga--------suru koto---- thing how to translate that, since I'm a beginner at translating ^^' "For example, it's the thing that my past self denies... (-datte xD))) and then this ends and the text switches kinda to another topic. (It's a lyrical text, no prose >//< ^^') After this sentence, it says (already translated) "It's okay to have said you cried" (Naitatte ii)

Ahhhh, so " 引き寄せ合って" is attracting each other?

and for 7) it's like
"雨音を奏で, 風口ずさむ, ずっとあの唄を。"

ohhh, really thank you for explaining it so well about 8) :3 いうように is "like you/he/she say(said in this context maybe)"...so for the whole context, what do you suggest as translation? I'm just a bit confused which person to add to which verb, if "you/ I said/like you said: see you someday" and "I/you/she is/was laughing continuously"?

and you're right about 9, I misread >__< It's like you said "逃げてきたんだよ", but I've never heard of this form, what is "きたんだ"? >///<
but with 10, I checked it as well, but it's written with the 目 kanji

The sentence with -datte is "例えば其れが 過去の自分を否定する事だって。"

v+こと・v+事 makes a noun out of a verb to describe the fact of doing the verb.
The same meaning is accomplished in English with +ing and sometimes tense changes, sometimes the addition of a word like 'thing' or 'something' or 'that'; there's no simple formula for translating this grammar.
毎朝走る・(He) runs every morning.
走ることは毎朝だ・Running every morning is (what he does).
Any decent textbook or grammar guide should cover this grammar point, if only because it's a part of the expression 日本に行った事がありますか which is always taught early on. (Well, the pattern, maybe not that sentence.)
"例えば其れが 過去の自分を否定する事だって。"
In this case, you have 過去の自分を否定する事 -> 'Denying (my) past self'.
(其れ can't be the subject of 否定する partly because things described as それ can't generally deny their past selves, unless you're talking about self-aware computers perhaps; and also because 其れ is the first part of an AがBだ structure.)
だって has a stupidly large number of meanings, pretty two sets, one for だって the prefix and one for だって the suffix, but in this case, it's #4 from here, ｢－だって｣ を英語で表現すると - Yahoo!辞書
You should be able to understand the whole sentence from there.

Ahhhh, so " 引き寄せ合って" is attracting each other?

Yes, if you're talking about 'attracting each other' in the sense of gravity.
With people, 引き寄せる usually means to 'pull close'. In your context I'm not sure if this is a metaphor or not, but even if it is a metaphor I don't think it has the same nuance as a person 'attracting' another has in English.

"逃げてきたんだよ", but I've never heard of this form, what is "きたんだ"?

来た+の(explanatory)+だ(copula)+よ(sentence final particle)

3)
just "promises"

7)
You missed very impotant commas in the clauses.

雨、音を奏で
風、口ずさむずっとあの唄を

These commmas show that the subject marker が is omitted here. Thus, 風 and あの唄 are the subject and object of 口ずさむ, respectively. (If the comma isn't there, as you wrote, 雨音を奏で is misinterpreted as "amaoto wo kanade (the subject) plays the sound of rain", not "ame, oto wo kanade the rain plays the sound".

8)
「またいつか。」 って、ずっと笑ってて is a request/soft order, as I wrote.

10)
There also is a typo in 目覚してよ。. It's actually 目覚ましてよ。. 目を覚ましてよ makes sense?
