You can stay there, no one will kick you out. KFC closes at midnight and none of the stores will open till the morning, but the airport itself will remain open. On the very top level, above the check in counters, there is a lounge that has tables and chairs you can rest in.
Yeah, after midnight the top floor of the airport (departures) is accessible even though there will probably be no departures. You can walk around there or sleep or whatever, no one will bother you.
