Quick thoughts:

1 - I'd be very leery here. Would depend on what I knew of the players. A pot size bet from early position says he has a very strong hand. I might call if I had a big stack, but I'd want the flush to continue

2 - Fold. A may re-raise and I'm in trouble.

3 - Bet about $4. If someone is trapping, I can get away from it. I want to bet enough so that one bad call from 'A' doesn't make it ok for others to draw.

4 - I'd fold so fast you wouldn't believe it!

5 - I'd be very careful here and what I do depends on what I know of the player and how many chips he has. If that is most of his stack and I know he aggressively tries to buy pots, then I might call. Other than that I think I'd bide my time. 2xPot is a big bet!
