| All 3 of the pics you've posted are Paphiopedilum. They all three look to be hybrids which willmake further ID impossible. I can tell you that the first picture in post #1 is a Maudiae-type paph, thesecond one in post #1 has Paph spicerianum in it, possibly it is half Paph spicerianum, and the paph pictured in post #3 is a Paph delenatii hybrid, more specifically, a Paph delenatii crossed with something from the Cochlopetalum Section.
The difference between Paphs and Phrags....well the difference that is easiest to explain is that they come from different parts of the world. Phrags come from South America, Paphs from South East Asia. but unfortunately that doesn't do much good when you're looking at a picture or holding a plant in your hand. The next most easily described difference is probably the leaves. Phrag leaves (with one notable exception) are fairly "grassy" meaning somewhat narrow-ish, evenly green, and pointed. Some phrag leaves are broader (besseae and its hybrids). Paph leaves are rarely pointed and while some are evenly green (mostly the warm-growing multiflorals and the cool growing complex) many are heavily (and I might add, delightfully) patterned. When it comes to the flowers, most phrags are green/white/brown. The notable exceptions are besseae (orange, red, yellow), xerophyticum (white), schlimii (pink), fischeri (dark pink), kovachii (huge flowers, very dark pnk/lavender), and andreettae (pastel pink). This means that phrags have a more restricted colour palete than Paphs. Also there aren't as many phrag species. Paphs come in an enormous range of colours.
