Answer 2

One question at a time for the purpose of learning technique.

Answer 3

You need an explanation, not an answer. And I don't care to explain that many at once.

Answer 4

Why can't you do these yourself? They're all pretty easy, but if you don't know how to figure it out, do a quick guess and check.
