Yes, the fins of a fish can grow back after nipping or rot.
Nipping happens when fish bite or pinch each other sharply, which mostly occurs when you keep incompatible finnies together in a small, overcrowded aquarium.
Some fish species like cichlids are naturally more aggressive to tankmates hence more likely to be nippers.

Fin rot can also be caused by a secondary infection on a nipped fin.
From experience, your fish will recover, and the fin readily grow back in pristine water with the appropriate quality for the species you are keeping. Treatment and using other remedies like Epsom salt will also go a long way.
