Your succulent leaf rootlets look great. If your soil is still damp then leave them alone to establlish further. Spray w/water bottle if you concerned that they are drying out. That way the leaves with delicate roots don't move around or get dislodged with burst of water flow. When plants get bigger and more developed, you might consider separating the plantlets into other containers so that the root systems of unlike plants don't get tangled. and so that like stays with like. I wasn't sure all the leaves in your pots were from same type of plant except for the last pic of Sedum Rub.(pork and beans). You could probably place near sunny window but need to check that soil is not drying out too fast or use the grow lights if no window with good light. Good amount of light for the right time helps to keep succulents retain their shape and compactness.
You are doing a good job so far!
