ICM isn't that big with that many players and you have the shortest stack, I would shove a little wider due to maintaining fold equity etc too. I would probably shove like K6s Q9o Q6s J9s A2s A5o Q22 76s or something? Can go a little tighter/wider if you like, of course.
Fold hand 2. Like A7-8o A5s or something given they are both randoms. He should be able to shove ATC nash wise, a random is prob more on average of like 65
I am still trying to get my 'eye' in on these 180s but I would push the K9o hand. Being the smallest stack here and doubling actually getting you some future fold equity I would be very willing to apply a large 'edge' so my default would be a bit wider, say K6o, K2s, Q8o.
edit: would have to get tighter if the field, especially the BB, were strong regs though.
I agree with the fold of the A4o hand, the ICM is still quite strong here (it is a little bit deeper than a 6 man bubble) using SnGWiz and guestimating at needing a large edge say 0.5% this suggests A8+,A5s,KT+ for the call. If it was the other similar stack in the SB it would be an easy call but you don't gain quite so much even when you do win against the big stack.
For future interest/possibly useful(?) the payout structures as the field narrows on the final table of 180s work out as:
2 left: chip ev, 100%
3 left: 69%,31%
4 left:: 58%.0 32% 10%
5 left: 53.5%,30.8%,12.3%,3.4%
6 left: 48.6%,29.2%,13.4%,5.8%,2.9%
7 left: 43.9%,27.3%,13.9%,7.5%,5.0%,2.5%
8 left: 41.1%,26.1%,13.9%,8.1%,5.8%,3.6%,1.3%
9 left: 38.3%,24.8%,13.8%,8.5%,6.5%,4.5%, 2.4%,1.2%
