Can anyone put names to these Aloes and possibly Haworthias.
The first looks like a compact version of A variegata, one maybe A aristata but I am not sure.

 

Just guesses ...
First one - looks like a variety of Aloe variegata but I can't get the pic to copy
2nd one - haworthia pumila donut - Google Search ?
3rd one - don't know but looks like a Haworthia
Last one - Haworthia limifolia (looks like mine)

 

Thankyou @Michael Hewett I looked up H pumila donut and it might be but there was another pic there which looked similar which was Gasteraloe Tarantula. It is probably one or the other.
Yes the other Haworth is limifolia.

 

My thoughts are

1) Aloe variegata x Gasteria sp ?
2) Haworthia pumula x Aloe longistyla
3) Aloe aristata x Gasteria sp ?
4) Haworthia limifolia. Looks a bit off, but that could either be growing conditions or it is a hybrid too.
