Do I have to enclose all nm cable that is exposed and below the joists in baseme

Have a small bathroom stall (more than a room) that was here when I bought this 1971 small house a few years ago. There is a 3 bulb vanity light and a switch installed and the nm cable runs down a post that attaches to the joist and then across the top of the side of the bathroom stall to the light.

There is also a nm cable running exposed inside the stall down to the switch. Should these be covered in a sheathing of some sort? What should I use if so?

Locally we are allowed to have exposed cable above 6' [?] along with the ceiling. Anything lower than that needs to either be in conduit or have a wall covering over it [drywall, paneling, etc]

Here if it's exposed it has to be in conduit or behind the wall.

NM cable is required to be protected from physical damage. Typically anything lower then 6' from the floor could be considered subject to damage but it is really up to the AHJ. Best way to protect the cable is to sleeve it in conduit as covering it with sheathing will do nothing and would still be a code violation. The conduit should also be connected to a proper box for the switch. I would recommend EMT and a 4x4" box with an industrial cover.

Here's some pictures of the small bathroom stall and the electrical cable. The nm cable runs on top of the stall side to the light and also up the post that goes to the joist and then to a junction up there.

I also don't like that wooden junction box that someone made. Shouldn't it be plastic or something?

Is there a metal or plastic electrical box inside the wooden housing?

Except for the possible junction box issue I don't see any code issues with the way the cable are run.

There is I believe, but I don't think it's closed if I remember correctly and the nm cables are not run through any type of cable connectors either.
