The one labeled "Casa de las Orquideas"... if the name is faded, is there perhaps an inventory number? Or part of a name? If so, you can inquire to casa@orquideas.com and they may be able to provide a name.
When you repot (in the early spring, not now) you have some landscape bedding plants... I think you'll want to keep this bunch away from your other orchids or you'll be doing a lot more repotting when they invade. Just a clear indication that the mix is broken down, since these are plants, no doubt, that love dirt.
