You did pretty good...
The first is possibly Vuylstekeara (or Oncidiopsis) Cambria, or one of the many similar hybrids. There really is no way to be sure. They are all variable and far too many to choose from. Cambria is used as a trade name for the whole group.
The second is most likely a Brassia, not an intergeneric hybrid like Odontobrassia. Again, a precise identification is unlikely unless we can be certain it is a species not a hybrid.
When you buy orchids without a complete and accurate name it is almost never possible to come up with a precise identification, but that is a close enough identification in either case here to point you to the proper instructions for care. It is best to repot these, or almost any commonly grown orchids, when there is new root growth just starting. A matter of watching and observing rather than a specific season or month. The exception would be if the media has broken down and is causing root rot, then the right time was several months ago, but right now is the best you can do.
