To borrow money for a friend means that you borrowed money from a third party on behalf of your friend. From the rest of the post it sounds like you gave your friend your own money, so in that case it's should be "loaned money to a friend"

The two (month deadline was passed / months have passed) and he didn't pay me back yet.

It isn't so(that/too) much money, but it is annoying because I feel disrespected.

borrow for -> lent to (lent when subject gave the money)
receive back -> repay (more natural)
they would repay -> conditional form of verb (for an agreement)

The two month wass have passed and he didn't pay me yet.

have passed -> present perfect when talking about passing of time from present.

Based on the context of your story, it sounds more like you lent the money and your friend borrowed it

The two month ws has passed and he didhasn't payid me (back) yet.

I put (back) into parenthesis because the sentence still works without it, but it's better to add the back.

It isn't sovery much money, but it is annoying because I feel disrespected.
