No. Not unless those outlets are each on their on fuse/circuit. And most room outlets are wired to the same fuse. That bedroom probably had a 15 amp fuse for the ALL the outlets. (1) 1000w will draw around 9 amps @ 110/120 volts. So if you tried to hook up all four lights and fans that's over 36 amps, which will either kick your breaker or start a fire.
Your best bet is finding an electrician to wire extra circuits for you. Probably 220 volt as it would allow the lights to run at a lower amperage. 1000w/220v= 4.5 amps. You'll be able to run more lights off (1) 220/240v socket than (1) 110/120 v.
All in all you need to do some research and make sure you do this right or you'll end up with major damage.
