A few id's needed

I have a few stapelids, not sure on genera or species. I dont know if you can id without a flower but hopefully someone can let me know what genus they belong to. Also another aloe looking one, i know the genus just cant spell it.
#1

#2

#3

#4

#5


The aloe looking one. You can see the plant on the right has speckled leaves insted of the barrs like the left hand side plant. Different species or different forms?

ok plant number 3 i believe is Stapelia leendertziae

and pic 5 i think is Orbea variegata

# 2 I think looks like a form of Epiphyllum sp. So I assume # 1 is also. There doesn't seem to be many species of Epiphyllum available, so when it flowers you'll be able to tell.

There's haworthia in the last pic - the barred one is H. fasicata (sp?) and the other one is possibly H. margaritifera.

As you know I am very new to this game, so if I get them right it's pot luck!

nah this first 2 are stapelids of some sort. Thanks for the help with the other 2, thats the genus i was thinking of.

In the last photo I agree about the H. fasciata (the standard form, compared to the superclone varieties), and I think the other one might be H. radula.
