2.
The Present Perfect Tense or Present Perfect Tense.
Either, as explained above.
3.Translate the following sentences into

OK.

OK.

2. Why couldn't I get in touch with you yesterday?

Only the second. You have to invert subject and verb for a question unless the subject is being questioned.(
Which came first? or
Who did that?)

In the future it would be more convenient if you made separate posts
for each of your questions instead of putting so many different ones
all in one post.
