Thanks for the replies so far guys!

Yah, thinking back on the hands I agree that I probably should have bet a few of them stronger.

I'm surprised at the majority saying Hand 1 is an auto fold, given the size of the bet, the pot, and our outs. Is the fact that villain is all in 30 (no more implied threat) make this call more or less EV? Should we call here if villain has a larger stack behind? (more implied threat, but also more implied odds if we hit our boat) Or is this a fold in any scenario?
