Vs a reg , the way you’ve played the hand I would happily call. Vs a fish I think I’d be sigh calling but expect to see 55 often. What I’ve found at low limit is fish tend to bet smaller with draws, typically 1/3 or 1/2 pot, and only pot strong hands.
Don't see how we fold. Hand is so underrepped. No one expects you to check call top two on flop and turn with 2 flush draws out and a bunch of straight draws. A greedy villain could value bet worse kings up or the same hand here. Also for value v can have 87s, 87o, 73s, 32s. Particularly combos with clubs or spades. For bluff QJ, Q9, J9, maybe some AJ that doesn't 3bet, T9, missed spades, missed clubs. Missed flush draw with a pair to block your two pair makes makes sense.
Bet, bet, overbet jam I think is an underbluffed line, but we can see you beating value here, there are lots of bluffs available, and it is enticing to bluff in your opponent's shoes when you look so capped. I think we should just call.
Flop check call vs large sizing is okay but on the turn with top 2 on a very dynamic board we have to raise. We can still have strong Kx like AK and K5s/K4s to call down vs a jam on.
