to c-bet or no? a few simple hands

a few pretty standard seeming "c-bet??" spots.
thoughts?

hand 1
my image is active. Button is 18-15-7 (vpip-pfr-3b) over decent sample. He has low fold to flop c-bet 43% and fold to turn cbet 33%, low raise flop c-bet 5%, high bet vs missed c-bet 80%. I c-bet just over 55% and he has be as 18-14-4. Cbet? plan? sizing?


MP2 ($20.20)
MP3 ($66.65)
CO ($19.25)
Button ($50)
SB ($50)
BB ($164)

edit: for those who are unsure about some stats i refer to
re bets vs missed c-bets:
ok - imagine you are on the button and call an UTG raise. They check the flop, you bet. This is you betting vs a missed c-bet. Say you bet every time you call ip pre-flop and are checked to on the flop - your 'bet vs missed c-bet' is 100%. It's on my hud pop-up extension under the various c-bet stats i have on my basic huh (= flop cbet, turn cbet, fold vs flop c-bet, fold vs turn c-bet). It's interesting. Especially if you like check-raising. Or if you like identifying monkey-checked-to types
