I would guess a desperately-in-need-of-more-light Graptoveria 'Fred Ives' on the 2nd.

As said above, hey both need much more light (I wouldn't think G. 'Fred Ives' for the 2nd one in that shape - leaves should be much bigger; photo below is from 2mo ago, they are even bigger now):

2nd one might be Graptosedum. Hard to tell with etiolation.

Okay, thank you so much! I bought both of them in these conditions, so Im not sure how I will provide more light now that winter is coming (Toronto).

Kaitlin, supplemental lights...(there are few of us close by to TO, using the lights...)

BtW, they still could be outdoors for a month or longer, depending on temps.

They will need much more light, otherwise will look even worse (more etiolated) during the winter.

oh okay. I had the E. pulvinata outdoors everyday since about the end of june, and only brought indoors last week as I moved into residence for Uni. For the etiolated second one, if it gets too tall, I can cut the stem and reroot correct?

Yes, you can behead, both of them (I see a cut stem in pulvinata's pot). But without good light, thy will continue growing the same.

Can't see the soil the first one is in, but 2nd plant seems to be in peat - not so good for succulents.

the first one is in a mix that drains as soon as I water it. like 1 part soil, 2 parts gritty small rocks/pebbles. I have to repot the second one as I just bought it today. What would be the best soil mixture for the second one?

Small pebbles - rocks are too big for the mix, they are OK as a top-dressing. If you have grit use that in the mix. Particles should be about size of aquarium gravel. You could use some perlite too, it is very inexpensive and available in many stores (it is good to rinse it or sift using the kitchen sieve to get rid of dust, and avoid breathing the dust). Mixing grit & perlite with small amount of soil should work well. This would work for most succulents.

okay perfect! thanks!
