Without looking at the other responses, I'll do a quick reply and see if our opinions are the same

1 - Call pre, as played, fold.

2 - Shove, I think he would usually bet bigger with a FH, most likely 10x that he won't fold.

3 - Fold pre

4 - Shove, especially attractive given you're slightly shallow.

5 - Fold flop

6 - Mehhh ship probably but not happy at all...NEED READS!! anything can help here
