Frozen lug nuts !!! I cant get em off !?

a family members car (96 Dodge Intrepid) was brought over to me because the front wheel caliper had blown out after the brake pads had either worn out or blew out. They said that no one had made a panic stop but they drove it with the piston blown out into the pad bracket forcing it against the rotor for over 15 miles at 55 MPH. I can only get 1 lug off after about a 1/2 hour with an impact an PB blaster. I have already tried just about everything but putting a floor jack on a breaker bar. Could the heat of the rotor have literally "WELDED" the nuts to the lugs ? What next ? It cant be driven at this point. Towing is out of the financial question ! can I heat them with a torch ? My compressor is only a 150 psi but I put at least 200 lbs of brute force to them OUCH ! I was told that when they brought the car over at 2 am this morning their wheel was actually glowing red from heat and after 6 hours is still warm to the touch !
