Haws are hard. Number 2 reminds me a bit of H. marumiana var. batesiana, but I think the leaves are perhaps a little too thin to be that; that and not clearly 'veined' enough like {{gwi:650136}}.

No 4 could be Gasteria 'Royal Highness' (pups)

Beautiful specimen Colleen :) Thanks for your help. I have that NOID Haworthia (pic no.2) for about a year and received it from a trade. A fast grower and it produces many offsets. I think it maybe will stay as NOID Haworthia, been trying to find its name.

@ Thanks Harry. I search online, could no.4 be Gasteria x haworthia cv 'Royal Highness'? not sure....

1. May be H. emelyae but also looks somewhat like (although less so) H. retusa v. turgida.
2. Could be, as Colleen says, H. marumiana v. batesiana.
3. Yes, Aloe 'Pepe'
4. Also looks like xGasterhaworthia 'Royal Highness' to me. May need to let it grow a bit more & take another look at it, though.
5. Could very well be Gasteria carinata v. verrucosa.
6. I don't think it's 'Opalina', but could easily be a cross (Pachy-, Grapto-, etc).
7. Maybe xGraptosedum 'Ghosty' or another cross (Pachy-)? Post when it blooms & we'll have another crack at it! =)

Rosemarie, I was hoping-waiting for you to stop by here......lol.
You are good at identifying succulents.
Thanks so much for your help :)
