All these seem bad.

1. I agree with Grif, 2 barreling seems better but i think I'd just check turn and hope his bluffing frequency on the river with a fd isnt high.

2. Everything seems terrible here. The preflop call, the 4bet, and the flop bet. Turn is std with how you played it but you messed up earlier in the hand big time.

3. I'd just call pre here everytime.
