The top one is extremely etiolated so an id would be just a guess. It is most likely some type of Echeveria. I’m gonna guess just by the leaves it could possibly be an Echeveria elegans. Do you have a before pic? Before it became etiolated.

The second pic is a Kalanchoe blossfeldiana.

Yes. And both need a lot more light.

Hi! Thank you for your comments! Here are more pics. I'm afraid I don't have a "before" pic. My friend was moving and going to throw them away. I thought I'd save them, but then realized I don't know what type of plants they are so I've been hesitant to do anything with them for fear of killing them. But I suppose I've been killing them anyway by doing nothing. The pots they're currently in don't have a drain hole. I have a windowsill that gets direct sunlight most of the day. Would it be too much to put these there?

Doing nothing might well have saved them! If you’d over watered in those containers they’d be goners. They need to be in pots with drainage holes in bright sunlight. But move them towards the window over a few days as they’re not used to the sun. The narrow necked vase is a particularly bad choice. You’ll see why when you try to get the plant out without damaging the vase😉 Once they’re repotted and in good light they'll need very little attention.

Are we sure the second picture is a Kalanchoe blossfeldiana? It looks more like a Kalanchoe carnea.

It isn't that easy to exactly ID plants that are etiolated. Your original photo wasn't really good for purpose of ID either. The genus is correct, and to know exactly what species is your plant, follow the instructions about putting it into better light, and repotting. Eventually, you could probably ID it yourself, or post again (photos of overall plant, and some details-close ups), and maybe we can help...
