If the pups are fully rooted, then they should be fine for the winter. However, if you want to keep them in a shed, just to be safe, and you have grow lights then there's really only two minor concerns.
1) Is the shed heated? Sempervivum do like to get cold so heating the shed like a house would make it harder for them to survive. Heating it a little bit, even keeping it around 0°F, would be fine.
2) How's the humidity inside the shed? This shouldn't be a big problem if the shed isn't heated too much, and humidity itself won't kill a Sempervivum outright. However, it makes it much easier to kill it by overwatering. This problem would only be compounded if the shed was heated too much. That would cause the perfect environment for rot to infest your plants.
It's certainly possible to overwinter these in a shed. Just watch out for the above issues.
