This one is not hardy to your growing zone. But since it can be divided, you might try as Bev said. Placing it in a protected area that also won't get moisture. It is usually a combination of cold and moisture that do them in.
This one should be hardy in your growing zone. It would do best in filtered light placement, not full sun. The more light it gets the more chartreuse color it will be.
I could be wrong, but I don't think it is Graptoveria 'Fred Ives', the leaves look wrong. Would not be hardy in your growing zone.
Graptoveria (XGraptoveria 'Fred Ives')
We cross posted Bev and Kyla. Wow, what a great arrangement you made to take indoors. It will be so much fun to see them next year.
Also, for the identity of the two tender type succulents, a good place to possibly get a positive ID would be our Plant ID Forum. There are some amazing people working in that forum help to ID plants.
