Eleven questions in your first ever post? That's got to be some kind of record!
Seriously, though: if you want to get a helpful reply, you should tell us what you've attempted already and where you're stuck, and possibly focus on one question at a time. (DON'T break it up into 11 separate topics and post them all at once!)
And if you haven't attempted anything yet because you don't know where to start, then re-read the chapter, asking yourself as you read each theorem and definition whether you can apply it to your current problem.
