The last plant, the leggy Echeveria... were you wanting to behead and restart that? I can't remember the conversation but if that's the case, use a sharp knife and clean up the dead leaves off the stem below the rosette so there is maybe half an inch of stem (not much more) left down there. Wait a couple days to a week before you put the severed head in/on soil, and wait another week or so to water.
You are very organized in your growing. And those cactus cuttings (no longer I guess) look well secured. I admire the discipline.
Some of the plants here in bloom... the bicolor aloe and the red-flowering Echeveria are hybrids I grew from seed. Turns out there's a volunteer seedling from the medusa (lower right) growing in the shade of the bumpy aloe next to it. (Not visible in the picture, still at the seed leaf stage.)
