cjloong, great buys you have there!! Which nursery did you get them from? I very rarely see such hybrids abvailable in Penang... funkychips is right. The first 2 are Maudiae-type hybrids, the first one showing more influence from either fairrieanum var. album or superbiens var. album, and the second one more of wardii or sukhakulii. The third one is a complex/novelty hybrid with Paph spicerianum. it may be more difficult to rebloom because spicerianum and its hybrids are generally cool growers. regarding medium, please look up the thread on paphs that funkychips started.. Feel free to add any questions.. Good luck!
