Two of these things are not like the others

Couple of imposters in this pot of Lithops marmorata seedlings. One is easy to spot, the other one harder. Extra kudos if you can guess what they are.

No idea what they are I'm afraid but I'm finding a bunch more interlopers in my Lithops seedlings from one particular source. I think nearly half have one or more additional species in them!

The plant on the left, and this is where I'm guessing, looks like there is some Pseudotruncatella involved. I'm going to be wrong here I think but the middle plant on the right of the picture is the other interloper. No idea what it is though.

Took me a while to spot it. I guess it's the same as the bigger one?

Well hidden, had to have my ~~nothing~~ morning coffee first! It's pretty orange, looks different to the other imposter, but I know nothing about Lithops.

Edit: Clearly the morning coffee didn't kick in yet when I was writing this...

The "easy to spot" is in the lower left and could be L. dinterops
The other is smaller and 2/3 rds up just above it a bit. Also L. dinterops but younger?

You mean the Lithops catlitteriana Tina Looks almost like it's evolved to disguise itself as a piece of "Tesco's finest" as they say!

Quite a good name for the little un
