Mediums? Deeps? If they are deeps you can use them for splits in the spring. If your bees are short this winter just put them on top of your hives. Not sure I understand exactly what you are asking though.
Close them up enough that bees can't get in but not so much that mold can start. The drawn comb will be damaged as it's robbed. A dead out with honey can be used (assuming you know why they died and it's not contagous) to supplement a hive that's low on stores. I did that last year when I knew there was an empty frame I would replace it with a "dead-out" one with stores.
