($16) Three awkard mid-game situations

[Zizz]

Forgive me if these are trivial. Just trying to work out some situations I'm not sure on. Thanks if you take the time look them over real quick.

Hand #1
I feel awkward standard raising here right around 15BB. I don't feel comfortable just pushing here either with hands like QJ. Folding seems too tight.

Hand #2
Somewhat similar situation. Not exactly sure how to play low pockets at this position and these stack sizes.

Hand #3
Kinda similar again. I feel vulnerable with A10 with so many people still to act.
