NL25 bad end of a straight on KQJ-board

[WantToLearn]

Hi 2+2, some more advice would be welcome, thank you very much!

<u>Questions:</u> I have the stupid end of a straight here. All went well, as they folded. Otherwise, I might have got lost.
1. What´s the correct reaction to a villain raising me on the flop here?
2. Is my bet size ok?
3. What´s the plan if there is a call and the turn card brings one of the many dangerous cards?

<u>Reads:</u> I have been there for a couple of orbits, don´t know the villains but first impression indicates they might be somewhat competent. E.g., I would like to assume that they understand that, say, bottom two pair is not the nuts on this board. General gameplay at the table was pretty loose-passiv.
