It looks like an Echeveria imbricata, especially since its tips are pinkish

Just a normal old-house window, not frosted. It's not etiolated ... but it is a bit limper than it should be, which is probably dehydration, since its rootball is mostly root and spends most of its time as dry as photographed ... I water it either by running the rootball under the faucet (at little more than a drip) until the dirt changes color or blocking the innner pot's drainage holes with my fingers (kind-of), so it soaks for a moment. If I top water it normally, the water just runs out the bottom without what little dirt there is getting wet. As you can see in the third picture, I can lift it in and out of its inner pot without the media really coming apart or losing shape.

That's an echeveria? Echies are supposed to look a rosette shape, and yours is stretching up like that because it does not have enough light. Any possibility of a brighter window location? Echeverias often lose lower leaves as they grow, so I wouldn't worry too much about that. Light is your problem. And possibly your pot..... I prefer a straight sided terracotta pot to the style you are using. I hope your pot has a hole in the bottom for drainage because that is the best condition for any plant, to have that excess water drainage benefit.

I don't have that plant to compare the growth pattern, but as far as I know it looks fine, growing well.
