Varsity Coach on JV bench

[Air JC]

Same type of situation with a JV game. Team A had 3 assistant coaches on the bench. I would guess that 2 of those 3 were fathers of the players and part time howlers. Team A took a timeout and one of the assistants asked me if I could give him a rule clarification. I asked if he was the head coach, he said no, I told him that if the head coach wants to use his timeout by talking to me then that's fine, but I won't answer everyones questions just because you have a seat on the bench. This brings up a question I have, is there a limit on the number of assistants, trainers, managers, etc. that can sit on the bench?
