Left is Senecio radicans, or string of bananas

Right is Portulacaria afra variegata

Middle looks like maybe Graptoveria or Echeveria, they generally have the same care, there's something called Graptoveria purple delight that looks very similar but I'm not positive

Does that bowl have a hole in the bottom? If not, I'd think of switching to something else, as drainage holes are pretty much essential for succulents so that they don't rot. Well draining C&S soil is also a must

I would suggest potting the grapto/echeveria and the P afra separately as well. PA tends to need a lot more water than other succulents

Thank you!! It does not have a hole but I will find one that does, you're the best thank you for your help!
