Chlorine is a halogen.
Combined chlorine is when the chlorine molecule has attached itself to other molecules in water. In other words it has "combined" with something else in the water. Those could be iron, manganese, ammonia or other things depending on the source water. Free chlorine is the molecules that are "free" in the water to do the disinfection.
