A word about cutting... I am very passionate about my Eche's. I do some things that many possibly would not do. Our plants are for our personal enjoyment as well as sharing both success stories and those that might not meet our expectations! What is important, IMHO, is 'Different strokes for different folks'... Ah the 60's/70's! Anyway, not all Echeveria produce a plethora of offsets, while others seem to abound in their efforts to reproduce. I'm not certain as to th ID of Denise's plant but it appears to be one that enjoys producing pups. As I started to say, I remove offsets because I enjoy having lots of plants to sell/trade or just give away. Next, the pups require energy which will limit the size of the main head, so I remove them as do I remove most flower spikes well before they open unless I've not seen a particular plant's flower. Keep in mind, some Echeveria grow as small to moderate sized rosettes and not a huge display making offsets questionable as to size of th main plant. Now, I don't disagree that the offsets can hide an otherwise unsightly tall stem. Here again, when my Eche's get to this stage, they get whacked!!!!! I don't like top heavy plants or bare stems. This process of beheading isn't any different than someone doing whack job on their favorite jade. This provides me with a nice looking head that will now grow new roots and a larger showy head and provide me with new offsets from the old stem. So in the picture we have an old beheaded E. limbicata, center back. The small rosettes will remain until their stems are long enough for me to harvest and I will toss the old stem. The plant, stage left, has no ID as of yet but produces lots of offsets from the base, which I will remove sooner or later and behead the main plant. The plant on the right was beheaded about six weeks ago. The stem has produced several new offspring which, hopefully, by September will be large enough to remove. The head is growing larger and IMHO looks much better down in the pot than blowing in the wind.... Bottom line we all do what we want to do and there is no "Right way" about it.

The 1st may be Sedum morganianum that has lost lots of leaves and is etiolated. Or some other trailing sedum... The Kalanchoe tomentosa may be goner (I wouldn't bother buying plant in such condition). If the 'partner' is the little think on left, that looks pretty bad - tip still shows sign of life, if the stem (have to cut it) is healthy, there is a slim chance it may grow. 3rd may be some sedeveria, I don't see much wrong with it; just pot I up and see. If the one with damage is healed over, don't worry much about it. If it is soft or open wound, cutting and re-rooting may be better.

Darer plant is Echeveria purpusorum. Cacti/succulent soil may not be draining as well as it is suggested - most ppl using it straight from the bag have suggested that it contains too much peat. Adding lots of sifted perlite usually helps some. They will like great light, but should be acclimatize to make sure they don't get sunburn.

Before you do, pls consider cutting it first. It's supposed to be a short, compact rosette like the other succulent rosette in your pic. (FYI: It's not supposed to be on a long stem like that.) I'd suggest you read up on succulents & Echeverias a bit, then behead that plant, give it time to callous & pot anew to start in on new, healthy re-rooting, further to Breton's suggestion above.
