I'm fairly sure that some of the stools have four markers, as they're totally four-way symmetrical. However, sitting locations tend to be more abundant than sleeping ones, so the "two-in-one-place" situation is less likely. Two-sided single beds are in the vanilla set, but aren't used often, I'd suspect there usually another bed in the room when they are. On the other hand, if a bed is placed against a wall, and there's a marker on that side, the game engine will keep sending characters into the wall to enter the bed, so having an option without the second marker is required.
I would expect multiple versions (left, right and both) to be provided. It's a while since I made a furniture piece, but IIRC the CS has to declare the marker, as well as the nif using it, so it may be feasible to point multiple instances to one nif, with the CS definition effectively choosing which ones are available.
And yes, it's possible to have multiple companions. I think they are subject to the same limit as any followers (eight?)
