No. 2 looks a Haworthia pumila

No 5 also looks like a Haworthia. The others may be Echeverias. It' very hard to ID plants definitively unless they have been bought from specialist growers, as so many turn out to be hybrids.

#5 looks like Haworthia limifolia(light starved)

#5 looks vey etiolated - stretched, and also light green color because of lack of light.

#3 is probably another haworthia.

#4 could be hybrid of Echeveria, perhaps of purpusorum. Hard to tell, perhaps better pic would help.

Close-ups of #3 & #4 may help to ID correctly.

Regardless of names, all succulents need same: very well draining potting mix; container should have drainage hole; lots of light. Water thoroughly but only when potting mix is almost totally dry.

I second the Aloe aristata ID fro #5..

1.) Definitely an Echeveria hybrid. No definite name, you can label it as 'Echeveria sp.' (sp. = specimen; it's what many growers use to name hybrids of unknown origins)

2.) Haworthia... maybe pumila? (I second hablu)

3.) Haworthia cymbiformis, from what I can tell.

4.) Most likely an Echeveria moranii

5.) Haworthia hybrid, maybe some aloe blood (xHaworthaloe). A bit hard to tell since it is so stretched out from a lack of sunlight.

sp = species?

#5 - good call palms & Breton ; it does look like very stretched Aloe aristata or aristata hybrid, now I see the 'tails' on leaves.

@rina

yes, sp. = species. I guess it was too late for me when I was writing!

@OP: Btw, the Echeveria and the Haworthia will not make for good companion plants. (Noticed you have them in the same pot.). The former like strong light and are typically summer growing/ winter dormant, while the latter prefer less light and are generally winter growers.

Thank you all so much for your comments! My succulent obsession is still in it's infant phase, so I'm really appreciative for all your help!

ianbrasil pls i want some jabuticaba seeds,can you help me?Maybe you need some seeds from Rumania,i can send to you
