Night layover at Shanghai airport, does the airport operate at night or is it closed?

Yes, Shanghai airport operates at night and this is 100%, personally verified. Flights arrive and depart around the clock, all infrastructure works the same as during the day, check-in and passenger clearance also operate. So if you wish, you can spend your waiting time either at the airport or leave it to stay overnight in a hotel or just walk around the night city. But, of course, exiting the airport is done taking into account visa requirements.
