So, Iām pretty this is a Crassula of some variation, but I was wondering if you could tell me, if each stalk is its own plant
Each stalk isnāt necessarily itās own plant, they may be connected below the soil and be one plant. But itās very easy to make them into their own plants, if you want, by just cutting them and waiting for them to make new roots, though! If you want to check if theyāre connected before cutting feel free to un-pot it and shake off the soil, see what itās doing under there. If it is connected just use a clean tool to cut them. Then donāt get the wounds wet, let them dry and scab/callus over for a day before you do anything with them. You can repot any parts that you donāt cut off if it has roots, just give it at least a week before you give it any water after repotting it. Succulents can rot if open wounds are soaked. Eventually the cuttings you made will grow roots, you can leave it laying around or take off a few of the bottom most leaves, let it callus, and stick the bare stem into some soil to wait for roots. Whatever you do just leave it dry, it doesnāt need any water and wonāt be able to take any up if it doesnāt have roots anyway. It can take anywhere from 2-4 weeks, or sometimes longer, for roots to appear, so be patient.
