Value Bets Costing me Lots of $$$...

Alright I'm on this 5/10 table, and basically I've started with/flopped monster hands...hands get heads up...Bet river, bet turn, and think I'm making a good value bet on the river only to get C/Red and having to pay of 20$...anyone see anything wrong with any of these 3 river value bets/anything else?

I guess my question is are all of these river value bets standard? It seems to me like they are, but I literally lost to 3 river checkraises in a span of 20 hands. Can I fold to any of these checkraises with no reads? Check behind any of these rivers to not pay 20$ to a c/r when behind?

Yes I know that hand 1 is not a c/r, just me betting oop.

Thanks in advance,
