Thank you!!
As long as the pot can fit over the one with the plant in it, you're good to go.
Don't worry about the sunlight in the garage. Plants can deal with less than ideal light conditions for a few days. After all, every day isn't a sunny day. The shed probably is good also. As long as they are out of direct cold and wind, they should be fine. Maybe throw a light blanket or something over the whole bunch of them!
