I'm afraid most unidentified Phals will remain that way. Even if you find similar looking ones they can't be 100% identified as the same because there are so many that look identical to each other in the mass market.

Some few do have identifiable characteristics which are not found in the mass market ones. Your last one is the most likely of the 3 to fit that category, but I'm afraid I don't know what it might be myself, or even for certain if it's an identifiable one.
They are just as pretty without a name though
Most of my phals are NoID.
