Hand 1:

I'd fold and let it go. This is a situation where I might not offer a continuation bet (based on opponent) because its unlikely that the flop hit hero. I'd probably be looking to bet/raise the turn.

Hand 2:

I'd fold. MP1 isn't moving in after checking without 1/2 equity in the pot. If either player has Axd then you will be less than 30% equity in the pot and most likely around 25% if the other one of them holds a set.
