At the flop he can have:

-Sets: 22, 33, 44 (9 combos)
-Straights: A5, 65s (20 combos). Didnt include 65o, because I think this is way too loose.
-2pair: 43s (2combos). I dont think he calls preflop 42s or 32s although he could do. Also I dont know if he want to raise those for value because of the straights that exist.

Latly what about overpairs? Does he raise those? And if yes, then which? JJ, QQ and TT?
Regarding oesds, at this spot any 5 has an oesd. I dont know if he raises those or call them. People dont bluff often also.

I think flop call was good. We have 20% pot odds. At the turn he could be having flush draws but if he only raised the previous combos I mentioned then he doesnt and we need to fold unless he has stuff like TT or JJ.

And for the river my call was terrible. If the river was a brick like a 3d then he might be having JJ possibly(although I doubt this) and we might consider calling.
