Default Removing a mean lug nut.

I had a lug nut that someone used an air wrench or whatever it's called on. I got my four way out and successfully stripped it by jumping on it. I got all the others off but this last one is a jerk. I used propane to soften the metal and went loose on it with a punch, hammer, and drill. I think that the heat from the propane bottle (plus me letting it sit overnight after the fact) has caused the lug nut to fuse to the stud because I think I should have gotten to the end of the lug nut by now but it isn't loose at all. I think I need to somehow remove the stud without taking the tire off. I am not good with cars and I don't have professional tools. I don't want to take it to a shop because I'm short on cash. How would I take it off.

Go to your local hardware store and buy some "PB Bolt Blaster". Spray it on there and let it sit for a day then repeat. 48 hours in it should loosen quite a bit.

Default 50% acetone 50% ATF

Try
50% acetone, 50% ATF, mixed. I used this once to remove a rusted nut, off a muffler. and it work good.
Good luck, hope this help. I'm dealing with stuck spark plugs right now..

Is it rusted?

What wrench are you using to loosen it?

If it's rusted, then yes, use some PB on it. A propane touch will do little to help, a hotter touch will get it off, but will weaken the stud.

If it's not rusted, just way tight, you need a good quality wrench. Go to an auto parts store or a hardware store. Buy a 1/2" drive breaker bar, that's just a long handled wrench.

Position the handle so you are putting your weight on it to push down to loosen. Make sure the handle is close to the wheel, not swung way out.

Using the vehicle wrench or those X type wrenches, often results in the socket end spreading as you apply pressure causing the nut to round off and not generate the required torque to the nut.
Buy the correct size socket for your car to fit the 1/2" drive breaker bar.

Exactly this, Harbor Freight sells a baseball bat sized break over bar(don't use it for tightening, trust me), get that and a good quality socket, and go to town. You could also find a piece of pipe and use it on your 1/2 ratchet, but you might break it. You have already damaged the stud beyond what I would reuse even if i could. So you put the bar on, and you twist that thing until one of two things happens 1) It come free and you replace the stud and lug or 2) you twist that lug and stud right off into two pieces...either way problem solved.
