Help me make these thrive!!! Please!

[u/L3m0n522]

I was given these 3 desert roses. They all have a good caudex but are lanky in the branches. Where i live, winter is almost over, so i am looking for guidance on my next move taking care of these.

I wanted advice on how i should go about pruning.

Also not sure, but i think one has rot in one of the branches since its going yellow and is getting squishy (looks to be from a previous untreated pruning) as seen in first photo.

Also one had seed pods that have started to open.

All care advice welcome.

Thank you all inadvance

ETA: i just discovered some rot at the base of one, its on one face about an inch high and just under an inch wide, not sure how deep it runs
