Is spark plugs are stuck what can I use to loosen them up.

Try a heavy duty penetrant, like PB Blaster or Kroll, not WD-40. Use a lot, and let it sit overnight. It's the only thing that might help. Then you are just going to have to work them loose. Whoever tightened them too much wasn't paying attention. It's good practice to smear a little anti-seize compound on the spark plug threads before installing. You will never have stuck plugs again, as long as you don't overtighten them.

My 2000 grande vitara is getting to much gas and it is missing some times

MISFIRE, how did you prove rich, caused????????
if that is true, it can be caused by:
  1. spark plug bad. (no spark causes, wet tips)
  2. too high fuel pressure.
  3. PCM stuck in failsafe (limphome) mode, scan it yet?
  4. got DTC errors??? scan it?
  5. misfiring when? hot , cold engine or both.?
  6. only idling , cruising up hills? or all time?
  7. leaking injectors?
  8. clogged injectors.?
  9. ECT stuck cold all the time (scan it is it 180F or more?)
  10. and more. cant go closer lacking all EVIDENCE.

I have a 2001 suzuki vitara it will run for about twenty minutes and stall.

which engine? 2liter?
do a tune up, read the operators guide, see the 60k mile listing.
follow that every 60k or it will stall.
if you did do your service, stalls can be caused by over 50 reasons.
I will list a few
1: not ever tuned up. if it has a cam belt , that too is 60k service.
2; bad engine cyclinder compression on 1 or more cyl.
3: bad spark, spark components dead. 1 or more.
4: stuck open EGR.
5: ISC stuck closed,
6: after 20mins the engine is not fully hot 180f+ bad thermostat.
7: leaking injectors
8: too high or too low fuel pump pressure.

each failure , is discovered with simple tests. using very inexpensive gauges.
ask for help, or take the car to any ASE certified mech.

2002 toyota highlander v-6, can I attempt to change the spark plugs? I'm concerned about the back 3, what's involved?

Look give it a try go slow. Hit them with WD 40 or equilivant. If you get stuck don't sweat remove valve cover(s) and its gaskets and plugs are right there.
It could be a little more work but you can do it.

I have a 2003 hyundau elantra. I unwisely tried to change the spark plugs while the engine was warm resulting in difficulty in getting them out. I have gotten all of them out except one. How can i do...

Ugh, this is very bad. If you have gotten wd-40 on the threads and yet you can feel it tighten as you are loosening it then the threads have galled. Sometimes tightening it back up is enough to loosen the threads that are seized to the plug.
However often removal will destroy the threads in the head and they will have to be repaired.
At this point you have two choices.
1. Tighten it up and hope it seats and leave it there. Then a few weeks later take it to a shop for a tuneup and hope they can get it out.
2. Or force it out destroying the threads in the head.
Repairing stripped threads in a head that is on the engine without removing it is not something I would like to do. The chance of getting debri in the cylinder is pretty high even with all the various tricks there are to avoid said contamination.
That being said there are kits to repair those threads.

Rear door light is on (SUZUKI VITARA)

The light button to the door is not pushed in enough to turn off. Tape it up or just may need a little WD 40, from just sticking.
