Heliotropic, First, it would be helpful to know where you are (at least area-east coast? (if not state or city, etc.) Also, might be helpful to know where you got them (big box store, nursery, show, friend). Now, seems to did pretty good naming for being completely new to succulents! Yay! More on that in a bit. One thing, the named cultivars used just single quote marks, not double. Your list...I'll make the names that are correct in bold...then, add notes about others. Top Row (L to R): Echeveria lilacina, could be a Sempervivum-need a closer pic please ("Ohioan"), Echeveria (not albicans or derenbergii) Middle Row (L to R): Need closer pic-might be an Echeveria or Sempervivum (of some kind), not sure-maybe an intergeneric (Sedum glaucophyllum is a tiny plant compared to this), Echeveria hybrid, could be one of many (probably not "Blue Curls") Bottom Row (L to R): maybe xPachyveria glauca (Echeveria "Spruce-Oliver"), xGraptoveria 'Silver Star', xGraptoveria 'Debbi' (not Echeveria "Metallica") If you could, show individual pix of the ones in question, that would help. =) This post was edited by rosemariero on Tue, Jan 28, 14 at 14:25

Pictured plant is about same height as yours - sorry I don't have photo showing it sideways. Here it is about year (?) earlier:I take all succulents out as soon as nightime temps stay consistently about 50*F. You won't need light if you keep them outdoors until late fall, when they have to come back indoors again. You could use CFL bulbs (I believe they are slowly fazing them out?), LED bulbs or fluorescent tubes - if those, either T8 or T5 would work. T5HO would be likely best, but they are more $ - so depends on how much you can/want to invest. And if you get more plants, more lights will be needed. MG cactus and succulent soil may be too peaty - can you get a bag of perlite and mix it about 50/50? Well draining soils are mix of particulates that are larger, peat is too fine. Many of use products like grit, turface, perlite, pumice, scoria - few of these together make good mix.

A little closer up pls, w/ more light, these are really too dark to say.

Could be Sedeveria 'Sorrento';). Sedeveria 'Sorrento' has these raised lines on the leaves. I think yours has this characteristic. My second guess would be a Graptosedum 'Vera Higgins';).
