I'll comment on a couple here.
Hand 1 - I would muck this preflop. I see no reason at all to play this hand. That said, I would bet more on the turn. I know you said the sidepot was only 10, but you are eligible for the whole pot which is 52.50. I would bet around 25-30 on the turn and check on the river if called.

Hand 3 - I would probably play this more aggressively. The Button could have any hand here, I would definitely reraise preflop and take control of the hand. If you just call preflop, I would lead out on the flop and see if my hand is good. Just calling down I think would maximize your losses in the event your hand isn't good.

Hand 8 - I like how you played this. However, how would you play it if you miss on the turn?

Hand 9 - I definitely wouldn't fold this preflop. You have a decent hand with position and it's only a minraise. I don't know why you would recommend folding this. Also, I would raise on the flop. That bet is definitely weak, and its following a minraise preflop. I raise on the flop.
