All three are hybrids, and it will probably not be possible to precisely identify them without information form the grower.
The first is a complex hybrid of the type sometimes called 'bulldogs', and there are dozens of similar green and white crosses. Someone may suggest that it 'looks like' something but there is no way to be sure.
The second might be a hybrid with Paph spicerianum as a parent, or it could be a complex hybrid strongly influenced by Paph spicerianum. Again, there is no way to be sure, but it is not Paph spicerianum species.
The third is possibly a hybrid of Paph stonei with a species or hybrid in the sequentially flowering cochlopetalum section (glaucophyllum, primulinum, Pinocchio, others). There would be fewer of those to guess from, but again it would only be a guess, and there are other species that could be involved.
