Honoratus to me doesn't seem usable at all, let's leave it to the ancient Romans. Honorata is at least somewhat usable but very unwieldy and not that attractive. I know a little girl named this and I don't think it works very well.
Probably exclusively Catholic; I've never seen either of them used IRL, but they could work as confirmation names. For more general use, I'd expect to see the shorter version: Hono(u)r, Honoria or Annora: all of them female.
