What’s the other 4? Gravity… and… Light? Kinetic? Magnetic?

Strong nuclear force: holds the nucleus of an atom together
Weak nuclear force: responsible for radioactive decay
Electromagnetic force: of charged particles
Gravitational force: attractive force between objects with mass

Not all decays are weak-based, though, and not all weak phenomina are directly related to radioactivity. That's just the only thing a layman has heard of where it's relevant.

The strong force only holds atoms together through a sort of trickle-down force, too, but that one feels like splitting hairs.

The person I replied to wasn't able to name the forces beyond gravity, so I think over-simplification and reduction to specific phenomena they would have heard of is appropriate.

Oh, absolutely. I was adding on for anyone else reading who might appreciate answer gravy. Sorry if it came across as critical of what you wrote, my bad.
