Hold on, I'm not sure what you mean by "running instances" here.
If you have multiple FFCs on the screen, and all have been assigned the same script, each script behaves completely independently. Other than the fact that they happen to have the same code, the only thing they share are the global variables.
Each script can have script member variables that act exactly like C++ member variables. For one FFC, each callback can read and write member variables that are also visible to other callbacks (of the same FFC only).
Then of course each callback has its function local variables, which are unique to each execution of the callback.
