I'd guess Aloe, maybe Aloe / Haworthia hybrid. I'd change that mix, removing the fine, peaty soil & replacing it w/ Cactus & Succulent mix w/ Perlite or Pumice (50/50 each). Otherwise it looks too peaty & not fast draining.

S. podophyllum.

Albinism in plants is rare but it does happen occasionally. However, the lack of chlorophyll (any sign of green or other pigmentation) negates the ability to photosynthesize so pure white or albino plants generally are very short lived. Unless they are parasitic, which is a possibility......I am not aware of any parastic plants that look like this however.

I have two NOID’s that I would like some assistance with names. I know Haworthia hybrids are difficult The darker one “looks” like it could be H. Mordor.
