No, you can just underdevelop or overdevelop just slightly. All the chemistry is geared to making a nominal print.

I've done this in extreme cold situations. It still didn't warm up enough to develop in 5 minutes.
It depends totally on what temperature the film itself is at. If you have had you camera and film exposed to cold temperature for a long enough time, its going to take a while to warm up. If it freezes, you make likely burst the chemical pod. Instant film should never be frozen.

Dunno. Someone else will have to answer that.

Its best not to try that. Instead, try keeping the film warm until you fully ready to expose the shot. Then do something to keep it warm while it develops.
