Welcome to MHF.
The part of your post I quoted is a great attitude and what we do here. We aren't here to do your homework but to help you understand.
As a rule though, we like one question per thread. Six questions is just too many so please pick the one you want help with the most and show what you have attempted, if anything. Then you can make another thread for the next question, and so on.
Glad to have you and hope you stick around,
