There is 1 referee and 6 other officials on the field at one time.
Usually there are four officials, a referee, two linesmen and a fourth referee to show the time or change in player, or if the referee can not take further part.
If you are talking about soccer than in total there are 23 (including the referee and 11 a side) but if you are talking about American football then i don't know.

The referee stands behind the quarterback on the offensive side of the scrimmage line, while the umpire stands directly across the scrimmage line in the secondary of the defense.
