There are a ton of Sedum species, many of them hardy to cold, but this one seems to me to be something like one of the Sedum rubrotinctum varieties. It's also called the Jelly Bean stonecrop, or pork and beans.
Again, they need a bright warm place, with dry soil. Don't be too kind to them, because they really prefer benign neglect.
The types that are not hardy to cold temperatures are best grown in pots outside for the summer, then brought in to overwinter indoors with very little water - especially if you don't have enough light for them.
