any ideas??

Not sure on the Haworthia's without checking some books, but the bottom right one looks like what was called Haworthia tesselata. The right hand plant in the second photo is an Adromischus, perhaps cooperi, but it looks like it could do with more light...

Hope that's of some help !

thanks mate, sure you helped Haworthia tesselata looks a lot like it, at least some strains.

yeah, will gradually give more sun, I just bought them

The red one must be Sesum spathulifolium purpureum it smells beautifully!
