as many as you want. Each teacher would presumably actually have around 20 completely trained battle ready pokemon they can use. if you're playing a teacher, you basically have license to pull strong pokemon out of your ass, including megas. No legendaries though, (and before anyone does, my teacher character will have the Mega Lucario)
