Thanks @Andrew Smythe!Plugs can be deceiving, they're often tighter than you'd think and take a fair bit of force to "break loose",. especially if they've been in there a while. A breaker bar would help with some leverage but you should be okay with a regular socket wrench unless someone put thread locker on them when they were put in. You really have to pull hard on them sometimes, don't be afraid. If you have the proper spark plug socket which it sounds like you do, you shouldn't worry about breaking off the porcelain part. Word to the wise, mechanics gloves are your friend here, when they break loose, you'll discover the best way to smash your knuckles off something...
The oil pooling in the plug cavity is likely from someone filling the oil without a funnel, if you miss the filler neck it'll pool around the plug and stay there. Good news is you'll likely find that #1 will be the easiest to remove.
When I say I couldn’t budge them. I couldn’t move them. I tried my darnedest. (Good tip on the gloves - ty!)
Re: oil where spark plug is. I had cleaned it all out totally before trying to remove them. Then noticed more oil in #3 after driving the car for a bit.
