The NEC doesn't limit the amount of lighting or electrical outlets on a single electrical circuit.
However I would put each rooms lighting on it's own circuit so that I could label the circuit to each room and then if I needed to work on the lighting in that room I could shut off the lighting to only that room and not the rest of the house.
For outlets I would put only 4 to 5 electrical outlets in each room on one circuit.
For my home I would want each rooms outlets on it's own circuit as well.
