In the general case, apart from the batsman, none of the batting team is allowed on the field of play. Instead, they line up several metres behind the batsman to watch and prepare to bat. However some variations on the rules make use of the 'disrupting rule', whereby 5 members of the batting team are allowed to enter the field of play and disrupt the fielders as they try to recover the ball. The "disrupters" have to follow three clear rules. First, they must not touch the ball with their hands (unless they are inside the bowling/batting area and are permitted to use their hands to remove the ball from the semicircle.) Secondly there must be no physical contact between a disrupter and any member of the fielding team. And thirdly the disrupters may not interfere with the ball when it is on its way back to the bowler.
