I would think the sedum would be alright to just go ahead and plant them. If the ground is dry you might have to give them some water so the roots can start into the new soil. The forest compost would be good for them. We use it here to amend our clay soil.
Your Graptopetalum and Echeveria are not frost hardy, so I don't think you would be able to plant them outdoors. But pots would be great. Once danger of frost is gone the pots can go out into your beds for the growing season.
Great plants.
