#1: pretty standard.

#2: Raise pre-flop if you're going to play. Flop call is bizarre to me, I would fold every time. However, you have to call the river IMO given the action.

#3: I fold river simply because of the sheer number of hands this board hits. Turn donk-bet to me looks like a decent made hand that suddenly realized it doesn't want to give a free card.

#4: Don't like it. SB could easily check the flop with a baby pair, then become confident when the Q pairs.

#5: Yeah, call, though I prefer betting the turn. I really prefer betting the turn.

I think you win 1, 2, and 5.
