The first one is probably Burrageara Nellie Isler. I am not sure which genus it belongs to now thanks to all changes, but you can search with the RHS search engine. I am not sure about the Dendrobium, but it looks like it has a latouria background.
The first one is most definitely Burrageara Nellie Isler (or whatever it might be called now, most people know that name though). It's a very distinctive one that is often sold untagged. It might even be Burrageara Nellie Isler 'Swiss Beauty' as that is the most common clone and yours does look like it, but while I'm certain on the Burrageara Nellie Isler I can't be certain on the clone.
Yes it is a Burrageara Nelly Isler but I don't know the exact clone either. On the label it says merely 'Cambria'. It surely looks like the 'Swiss Beauty' clone.
