Those are stroke judges. They make sure each swimmer is swimming with correct technique. There are many rules about each stroke, and if a swimmer is doing an illegal technique they can be Disqualified
Things that can get you disqualified include:
Touching the bottom of the pool
Touching the lane line
False Start
Preforming the stroke wrong (doing a freestyle kick during a breaststroke race, etc)
Staying underwater too long after the wall (That's what the colors on the lane lines are are marking)
Not touching with both hands on every turn (in breaststroke and butterfly)
Taking more than one kick per stroke (in breaststroke)
Turning over too early (in Backstroke)
But olympic swimmers know better than to do any of those things, of course
