Hand 1: Ugh. Call the flop! Since villian is so horrible like you say, I think you probably stack him if the flush hits. What makes you think your overs are live?

Hand2: Standard. Punish those damn shorties.

Hand 3: Turn push sucks. 0 FE and most likely an 80/20 dog here, with the slight possibilty of drawing dead. I probably call the flop bet here, and if he shows weakness on the turn then you can steal the pot.
