So my dad and i were trying to take some spark plugs out of my truck and we got three out but we couldnt get the other three out because they would loosen and then tighten back up. How could we get them out?

Take a look at this recent thread.

The good news is that they turn. Try spraying any kind of lubricant (wd40, silicone, engine oil, ect) around the plug where it meets the head. Get a good pool of it if you can. Continually tighten and loosen the plug and let the oil work its way down the threads. Even if its a quarter turn and it takes 100 reps its better than stripping the threads out.

New plugs get antisieze and if their not a PITA to get to take them out twice a year and change them or re antisieze them.

That method is solid advice.
