The others needed persuasion......
Spark plugs from Left to Right.....

you can see oil at the top of the threads on 3 of the plugs...

YIKES!
IIRC, plugs only require (something like) 19 ft# of torque. Stripping the aluminum threads immediately came to mind - even if they are "only siezed".
On installation, I dab the tip of a finger in some anti-sieze goop, and make a single swipe (perpendicular to) across the threads before reinstalling the plug.
In 55 years of changing plugs I've never had one back out, nor require more than a gentle push on the ratchet handle to break it loose. (And, once the initial torque is broken, the plug usually unscrew with twisting the extension with my fingers...usually.)
Obviously, those threads didn't strip out; no harm done. But, I know you'll like the anti-sieze when you remove them next rime.
