hi all! I have a jade, a fairy washboard, and a don't-know (can anyone id?) I would like some advice on

I took over for them from a sister who was likely overwatering and generally neglecting for a year or two

don't think they've ever been fed, have Foliage Pro coming in the mail if they would like that?

• the dontknow once had many stalks which have all rotted and fallen out except one, which now seems to be doing well some months later and is steadily putting out new little nub-leaves
  - for this solo guy the pot is of course much too big and I was wondering how best to repot him procedure-wise and in what size/shape pot?
  - I have ingredients coming in the mail for a proper gritty mix as i've seen on here so i'll use that, planning to replace all of these plants' mix with it actually
• the washboard has really exploded since I took it over, having a baby which has grown to almost its parent size and they both continue to grow -- does it look like it needs to be repotted yet?
  - also a few odd appearances on them, brownish "chipped" looking tips, brownness at the base of some leaves, a little patch of yellowish discoloration on an upper leaf, and what I believe is old sunburn from sun overexposure at the very base leaves of the parent plant, but just want to make sure
  - I water this one in particular very rarely, possibly too little?
• the jade - growing steadily and only watered when the leaves are thin and soft, I think there is maybe even a white flower coming in on one stalk
  - it's way leggy as you can see, never pruned, what's the best way to prune? how far down etc?
  - it also has a visual thing I haven't seen on other jades, the "pores" seem "clogged" on a few of the largest upper leaves, with something beige, I don't think it's bugs or fungus because it's been like that for some time and otherwise fine
  - also, are jades always supposed to be glossy like they are in some photos? only the newer growth on this one are glossy, it's also a somewhat darker duller color than some jades, it is getting as much light as it can in this house though
