I don't see any substantial roots in the photos. In general, it is best to wait until each cutting has at least 3 or 4 roots and each root is at least an inch long. That's the minimum and it is often best to wait beyond that. There is no rush. When you do pot them up, put multiple cuttings together in a single pot that is just barely big enough to accommodate the cuttings, roots and enough potting mix to barely cover them.
