Help with Relative Pronouns

[Rei Yahya]

I'm not very good with grammatical terms, but 'relative pronoun' is the term I found to explain when a verb affects a noun.

彼女は食べていたりんごを兎にやりました。
She gave the apple she was eating to the bunny.

会社員は駅へ行く途中でお母さんの彼に買った財布を落 としました。
The office worker dropped the wallet his mother bought him on the way to the train station.
(This sentence will probably definitely need some looking over. )

私達は旅行した国が美しかったのです。
The country we traveled to was beautiful.

What I would like you to teach me if you could be so kind, is how to say something akin to...
"That's another thing I don't want to do."
"All the plates we washed are in the cupboard."
"Two more of the people we talked to came back."

Where would 'another', 'all', and 'two more of' fit into these relative pronoun cases? Yoroshiku onegaishimasu.

Those are all examples of relative clauses, with the relative pronouns omitted.

会社員は駅へ行く途中でお母さんの彼に買った財布を落 としました。

が can't be replaced with の in this case.

は and が part 2: subordinate clauses | Japan Forum
This might be a bit advanced, but 会社員は駅へ行く途中で（彼の）お母さんが買ってくれた財布を落としました sounds more natural.

私達は旅行した国が美しかったのです。

は usually can't be used in the adjectival clause. (It's used only as the contrastive marker.)
は covers the whole sentence. You can use it in the first two examples, since the subjects of the main verbs やりました and 落としました are 彼女 and 会社員, respectively. Whereas in the third example, 私達 is not the subject of 美しかった. So, it should be 私達が/の旅行した国は美しかったです.

Where would 'another', 'all', and 'two more of' fit into these relative pronoun cases?

The order of words could change depending on the sentence structure.

That's another thing I don't want to do.
それが、してほしくないもうひとつのことです。
それが、もうひとつのしてほしくないことです。

There is another thing I don't want to do.
してほしくないことがもうひとつあります。
もうひとつ、してほしくないことがあります。

But 洗ったお皿をすべて, 話していた人がもう２、３人 wuld be more common.


Incidentally, "relative" is the term in English grammar. There is no equivalent to "relative pronoun" in Japanese, and "relative clause" is called 連体節[れんたいせつ] "adnominal/adjectival/attributive clause" in Japanese grammar.

As Mike pointed out, there's no relative pronoun in your sentences.

Also two particles of the 3rd sentence need to be corrected:
私達が旅行した国は美しかったです。(の was deleted)
The country we traveled to was beautiful.

As for your question, "another" "all" "two" are to modify the main noun followed by the relative clause.

"That's another thing I don't want to do."
私がしたくないもうひとつのこと。
"All the plates we washed are in the cupboard."
私たちが洗ったすべての皿は食器棚にあります。
"Two more of the people we talked to came back."
更にふたりの私たちが話した人たちが戻って来た。

Japanese translation given here is not always the most common/natural, I made it closer to the original English to give you the idea of "all" "two" "another".
