They are all albino except for #5. They may be Bells, but I don't really know for sure:
1: reverse stripe albino
2: possibly aberrant since the tail (but not the body) seems striped
3: superhypo (may be snake eyed, hard to tell)
4. carrot tail
5. hard to tell. Possibly Mack snow, possibly enigma. Does it have solid eyes?
6. partial reverse stripe
7. normal albino.
