there are 2 refs and 2 line watchers
There are usually 2 referees in a volleyball game. One is on the stand and one is on the floor.
Yes. One referee. Two line judges.
The games stops for a short time and the referees go to talk about the call and agree on who's right and who's wrong.
Five seconds. But not very many referees go by this rule in levels such as high school and middle school volleyball.
i think there are four referees.
There are four referees in a baseball game.
3 referees are in soccer and football

Volleyball has two referees, one to handle ball calls, and one to handle substitutions and timeouts. Also the first ref watches the offensive side while the second ref watches the defensive side.
you have to call the balls that hit the line or go out when the ref can't see
