Laura It shouldn't be difficult to separate them - there seems to be lots of space between individual plants. You can behead them - chop off top part of plant (best to use sharp knife), let callous and pot up. You can pot up lower part (leftover trunk with roots) & you could get some new babies sprouting from it. It would be good to improve your potting mix, this one looks pretty peaty (hard to tell from your photo). They would enjoy more gritty mix - much better drainage. There are some skinny & tall plants in the background - are they succulents? Edited to add: here is a thread with very similar question and good photos: beheading echeveria Howard (bikerdoc) is giving excellent advice & photos showing 'leftover' trunks growing new plants.

Many thanks my friend. I'll check that out tomorrow, (it's bedtime here.) Really appreciate your quick response.

Lolllll, at this time of year, I always seem to burn up my plants, so I like to keep most of them in bright shade. I'm also negligent when it comes to watering, so bright green with a bit of blush is what I get wit has this plant. I'm happy with that ☺ Yes, I do keep my plants under lights in the winter time. This year I'm setting up a bank of LED's. Nothing fancy mind you, I tend to be rather lazy & repotting, occasional watering & inorganic mix is the extent of my care. I haven't been at this very long, my oldest plant is probably 6 or 7 years old. My aim is simply to keep these lovely textured plants as long as possible. I have recently stopped replacing plants that don't perform well for me.

DP - HERE. It make take longer than 3 hrs for someone to ID....and it already was. Top plant is too small IMO.
