Lithop and queen of the night seedling?

Good afternoon, I was given some seeds from a friend, never tried to grow these types of plant from seed. I have had some germinate and I'm wondering if they are actually what I was told they are? First pic is "split rock" seedling and then the queen of the night seedlings, thank you.

 

All I would say is they look like cactus seedlings.
Not like Lithops I dont think.

 

Certainly the second pic, queen of the night are supposed to be an orchid type cactus

 

They are difficult to ID at that stage.

 

I'll stick with them, I agree they all seem to look alike at that stage.
