Are 5 players allowed to play in volleyball rules?

Answer 1

6 players are allowed on the court at one time for one team at the beginning of the game. If a player were to be injured during the game and there are not any substitutions, then you can continue to play with 5 players.

Answer 2

if it's for fun, like it's just for PE or a family thing, that's ok. but if you are in a serious game you cant play until you get 7 players cuz you at least need 1 substitute.
