Second one looks pretty standard, so I didn't check it out.
For the first, CO should be jamming 19 or 20%. You can call with 99+/AJs+/AQo+, and I think the reason is that you'll either KO the guy and have a big stack, but if you lose you'll still have a workable stack and remain well ahead of the shorties.
To reduce variance, you could fold AJs and AQo, but I'd guess that anything that nets more than a dollar on average is too good to pass up.
Note that the ICM pressure means that the CO can jam around 20%, but none of the three people yet to act can call with more than 5% (edit: BB can call 12% if it's just the CO jamming). Fold equity is a thing. But AK is also a thing. If the CO had folded, you can push an incredible 65% of hands.
