If four batters are swinging outside the dugout, is this legal according to NCAA rules?

According to NCAA rules, batters are not permitted to swing their bats outside of the dugout area, as this could potentially lead to safety hazards for players and bystanders. The dugout is designated as a safe area for players to prepare for their turn at bat without endangering others. Allowing multiple batters to swing outside the dugout could result in injuries or impede the flow of the game, which is why it's against the regulations. Thus, it is illegal for four batters to swing outside the dugout.
