Many succulents in that pot, probably getting really crowded.

With the tall ones, you probably won't kill them out if you tried, lol. This kalanchoe known by common name as 'Mother of thousands - or millions' will keep reseeding (drops numerous tiny plantlets that grow with ease).

Difficult to ID all plants, I see some huernia (maybe schneideriana?), echeveria ('Topsy Turvy'), possibly some sedums and pachyverias or graptopetalums too?

If my plants, I would pot them separately, into well draining mix, into containers with drainage holes and give them lots of light (acclimatizing gradually)

Oh boy, too overgrown, too many and they aren't in the best condition. This is like to see the plant version of negetle dog with badly tangled fur.

However, I thing you can save a good number of them and use cutting from the other to grow new plats.

First identification:

1)Kalanchoe daigremontiana "Mother of Thousands". Rina is right, that plant is a survivor, if it dies (which is almost imposible) its children will take its place.

2) Echeveria Runyonii 'topsy turvy" It looks good. in a new pot it will look nice

3) Huernia Schneideriana/keiensis/zebrina... it's hard to say without flowers. They look bad, but probably you can save some cuttings

4) Sedum nussbaumerianum (?): very pretty, they will make a nice decoration

The others look like some kinds of sedum (sedum glaucophyllum? maybe?)

Ok, firt buy/look for some cacti and succulent mix and as many pots as you have types of plants (preferibly terracota) with draining holes. You could buy a bag of pretty pebbles, grave or little rock for decorative purpose.

Now, take out the plants carefully trying to not damage the roots and check if they have any pest or signs of rotting.

- Pest: it will depend of what you find. Come back here and tell us what is wrong

- Rotting: you can cut the affected part until the stem looks healty (it should usually be light green, if the center it brown, keep cutting it until it disapears). Leaves them in a dry place until they form a callus and some roots stat to appear (arround a week)

If anything is ok, you can plant them in their new pots, and do some search about what they need. Succulent doesn't like to watered frecuently, usually once a week in summer and once a month in winter. They also love light. Full sun or very bright shade.

You can also ask the experts in this forum if you need help. Good luck :D

I think that most of the plants are very salvageable, most don't seem to be rotting, rather are etiolated. You could have roomfull of the plants in no time :)

Rina: I mostly said it for the huernia and the suspicious yellow branch. Still, some cuttings will be required to make them look pretty again after the etiolation

Lorien you are right - that huernia branch and whatever is left of the plant it was is most damaged, dried up and perhaps rotted. I was thinking about many cuttings, sorry I didn't say that...when I said many 'new' plants :)
