I have 16 hrs layover at Beijing Airport what are my options for hotel room or lounge and price?

The three terminal buildings have hourly lounges. You can check in to have a good rest. The fare can be CNY480 or more for overnight stay. Or stay in a hotel nearby. I know the Xinyue Aiprort Apartment, which offers free pick-up and see-off services from/to airport and it only takes 5min.
