I will call the mechanic tmw to verify where the leak was coming from.
Could the fact that spark plug #3 not being able to come out affect the numbers?
What other info do you guys need?

That's what I thought, stalagtites and stalagmites on the valves and seats. If the car is really sweet otherwise, this is what you have to do. First, drive the car for 100 miles or so, and try to do it in one or two drives. This will "clean" the valves, and should be done following an oil & filter change.
Then, on a barely warm engine, remove the left, upper, rocker arm cover, and spray a good quality product (PB Blaster, WD-40, etc.) around the base of #3 plug. Break the plug loose with an appropriate tool (you're on your own with this, I can't "feel" what you will feel). If it kinda turns a little, leave it sit and let the penetrant work for about 15 minutes. Then screw the plug back in, and then back out. Do this with patience, it might take you fifteen or twenty tries to get the plug out, but it will come out. If the head is damaged, the engine might have to come out/apart. Re-do the leak down test.
Remember, each cylinder is tested as an individual, and the other numbers will not be affected by #3, but that plug must come out anyway. BTW; there is nothing alarming about the leak down numbers (other than #1) now that I know that the car was in winter storage, and maybe not even driven far enough to get up to operating temperature.
You must try and convince the seller, if the car is a good one, to have that #3 plug removed. Does the seller have a mechanic? If not, who's been caring for the car?
Was the rest of the PPI NOT performed because of the leak down numbers?
