I think this is a misunderstanding about that table. If you look in the Input Verification and Results Summary, Zone Summary there are only 4 zones in the model for 630.39 m^2 of conditioned floor area.
What you are seeing in the Lighting Summary is that there are multiple lights objects in each zone. For example, THERMAL ZONE 1 has four lights objects in it. The first of these is '90.1-2007 - PRISCHL - CAFETERIA LIGHTS 2'. In the OSM, this was associated with Space 105 through Space Type '90.1-2007 - PriSchl - Cafeteria'; the load had a density of 0.9 W/ft^2. Space 105 has a floor area of 425.9902 ft^2, so in your final EnergyPlus model this is converted to a lights object with fixed wattage of 0.9*425.9902 = 383.39 W which is assigned to THERMAL ZONE 1. Does that make sense?
