playing second or third pairs on flop

this is kind of general, but i'm having a lot of trouble when i hit a flop but the pot is multiway, and there are overcards. say for example i have K9 and the flop comes Q92 for example, or maybe i have K6 and the flop is QJ6. when there are 3-4 players in the hand, how should i go about playing these? early position i'm thinking bet the flop, if most people call check/fold the turn UI, in late position i'm not sure because someone usually bets out before me.

it seems you are basically drawing to very few outs in a multiway pot, since you are most likely behind when you get several callers. should these hands simply just be thrown away?
