Unfortunate situation.
When you cut eggs you break the systems that kept infections out and moisture inside at the correct level.
The best time to cut is ideally after the first egg pips naturally, but even then they need a bit of care daily to prevent problems. You need to watch out for any fungus/ infections and monitor the thickness of the albumen at the same time to be able to top it up with incubator temp water to stop it getting too gloopy.
In your situation I'd get some cotton buds and remove any clumps/ fungus spots in the egg white and top up the eggs then re-dial in the temps and cross your fingers.
The time they take to hatch is entirely dependent on the temps they were incubated at so nobody can say exactly when they will try and leave the egg without that info. There are a few clues - are their noses out of the egg white and are they breathing air? Are the heads at the top of the egg all the time? How big of a window did you cut?
Pictures would be the most reliable way to let people see the condition of the egg white etc to try anmd help more.
