usually 6 or 5 but depends ...
They have to pitch the complete game...
First off all it would depend on what the score of the game was and how many batters were faced. There is anywhere from 150-300 in a 7 inning softball game. It would depend on the level of play, the skills of the pitchers, and the umps of the game.
10 teams are in fast pitch softball.
However many you can until, you pitch out
There is 3 outs in the bottom of each inning and 3 outs in the top of each inning so there are 6 total outs in each inning.
three outs per inning
i know in fast pitch softball it is 4 outfielders allowed on the field at once
