1.i would shove , just cause he is short stack and he didnt go all in (ussually they do that only KK+)
2. fold, AQs aint good there , actually i fold AQs to any rereraise
3. fold, on that stack to lose i would only call KK+

anyway, on all 3 you have to little hands on them to make a good decison about their playing style and ranges.
