Very good looking plants you have
I do not have semps I think in my collection, or if I do maybe I just do not know if it is a semp. I grow various succulents in containers too, looking at your lovely ones, I think the container is rather deep, it looks very nice, but I always plant my smaller, younger succulents in a shallower container, then I move them to a deeper one like that when it is much older. I find that even if I use good draining soil, if it takes longer to dry out, it also damages the roots, succulents just hate prolonged wet conditions.
