My preference would be to bring them back for next season, and move them at the deadline, if we're out of the race, or next offseason.
My second choice would be to move all of them right now, assuming the return was satisfactory.
Caveats:
1) Of course, if any of them are willing to sign a reasonable contract, you do so. It would be great to extend them 2 FA years, but I don't see them willing to do that.
2) Of course you trade any of them if the offer is extraordinary.
