The Hubble telescope wasn't unique. It was simply the first one that was pointed away from earth.

For the JWST, is there even room for a 2nd telescope at L2?

There's room for a lot of them, it will be in orbit around L2, not exactly in L2.

But L2 is just one point

That's an abstraction. In reality, what we call "L2" is an orbit around the L2 point. No shortage of room.

I was thinking since the point is so unstable, the orbit must be extremely small...

Boy was I wrong. The orbit is about the same size as the moon makes around the earth. [0] Its HUGE. We would run out of material to make satellites before we ever ran out of room.
