What are the names of these "succulent" succulents?

[SunnySideUp]

I saw some plants at Meijer's today and I knew I absolutely had to leave with some to add to my windowsill collection. Hopefully in the roughly 3 months until I get my tortoise (assuming that warmer weather comes in a predictable manner) they will be all clean of pesticides and ready to be eaten.

I'm trying to get better at identification, but I wanted your opinions as well. I have no idea why so many places don't label their plants! I have yet to come across even one properly identified potted plant.

Anyway, the first plant I got was this succulent, which I believe to be a Echeveria (Hens and Chicks)



The next one I hope is some type of aloe, although it looks a bit pricklier than some aloe veras I've seen on here...Maybe an Agave?



Please let me know what you guys think! Hopefully I'm not way off base.

It looks correctly identified to me, but let's see what experts say.

I agree, haha Thanks for your comment, though! I'm mainly confused about the second one.

first one does look like a type of echevaria, or perhaps a sedum, second one looks more like an aloe than an agave though: agave are new world succulents, aloe are old world: africa, middle east etc.
