Hi vanamonde!
I don't believe that the OP posted a picture of a true miniature phal. He received it from his daughter, and she said that it was a mini orchid. I don't believe that is the case.
I believe Lucy's description is correct for dwarf/miniatures, though all of mine are the full size. I've not grown any of the minis.
As to the #4, and #5, an anomaly maybe? I'm not sure. I was hoping to see additional pics from the OP, but alas, the thread was marked identified, without additional photos.
