Some kind of pachyveria or graptovereia. Medium level sunlight required for it to thrive, somewhat tolerant of watering. Not hardy, keep indoors during winter. Place in soil with decent drainage, preferably a plastic pot with big drainage holes.

I think I see some moss there? Pls. remove it as it keep plants too wet for too long.

These are very easy plants to grow, but as mentioned above, they need very good drainage. Get some Cactus&Succulents soil and a bag of perlite. Perlite should be sieved or rinsed. Mix those two 50/50 to get better drainage. They will need lots of light - after repotting, move them slowly into more and more sunlight. Succulents need lots of light; 6 hrs/day is usually minimum.

If you read few of the threads, many mention well draining mixes made for succulents. This works for all of the succulents, not only your plant.
