9 but there can be ten (you can play with an extra outfeilder in tee-ball)
5 to 8 players play at a time
Depends on the league. In MLB it is 9 on the defense at one time.
nobody has the time
Only 11 players from Manchester United can play at a time.
A total of 22 players play at a time in a football match, 11 players in a team.

2 at a time
At any time, there are 9 defensive players and 1 to 4 offensive players on the field.
On the field nine players will play at a time, although rosters range from having 12-18 players generally.
Well, let's see. If you divide the players evenly their will be 11 players on each team. However, only 9 players on each team can be in the lineup at any one time.
