Hi! Those are some lovely catts you have! and no, those are not stupid questions, as there are no such thing...
A primary hybrid is when a species and a species are crossed to make a primary hybrid.
A Hybrid is when a hybrid or primary hybrid is crossed with a specie, hybrid, or a primary hybrid.
Also, if the orchid is a species, then the name would be lower cased, (example: C. skinneri) the name is lower-cased, if the plant is a hybrid of any kind, (hybrid primary hybrid etc.) it is capitalized. Example: Lc. Gold Digger)
In this case, all the catts you have a hybrids, you have some were it is a hybrid x a Species, but the hybrid x species is still a hybrid. (because it's just adding a parent). I hope this helps and lovely cattleyas you have!
