ใฏใใใพใใฆใใฌใฆใขใณใใใ
I could translate your sentences. I wrote them with kanji and kanas.
Hiranagas in blankets show you how to read the kanjis.
And I checked your Japanese.
(1)ใ ใใใใฎใใใใ -> ใ ใใใใใ.
It's better and feel natural Japanese.
When we say like your way, we say "ใขใใใชใฎใใใใ".
(2)ใใ
ใฏใฃใใ -> ใใ
ใใฏใฃใใ
It has prolonged sound.
I think non-Japanese people often drop it because of roma-ji system.
(3)ใฉใ ใใใใจใ ใใใใพใ -> ใฉ
ใใใใใใจใใใใใพใใ
It's the same as (2).
And you end "ใใใใจใใใใใพใใ".
I think this is translated "Thank you in advance" into Japanese.
Generally, when we ask someting, we end "ใใใใใใญใใใใพใ".
When we get some response and we show "thanks",
we end "ใใใใจใใใใใพใใ".
Ganbatte!
