I always go to the “San Pedro Mastery” channel on YT. That guy is super credible and every time I have a columnar cactus question, he already has a video on the subject. I am not associated with the channel at all so this an an honest endorsement.
The white-green areas on most of the cactus look like they have been bleached by the sun. I’m guessing that the person who was caring for them had the cacti in heavy sunlight. I recommend putting them in a shaded area.
The thin ribs are possibly due to them not getting enough water. These cactus can take a lot more water than normal cacti.
The top of the last pic looks like decent growth. It looks like it’s starting to thin, probably because the plant isn’t doing too well. When the cactus gets thin and stays thin with new growth, it’s usually due to lack of water and nutrients. Specifically the plant thinks it’s winter time which is why it grows thinner.
In the first two pictures with the yellow-green spots, is it soft to the touch?

I told my friend to put them in front of a window with much light. But she put them on the ground close to a small window so they had very little light for months, while she gave them way too much water. So when i got them back i've put them on the balcony in the sun where the rain normally never reaches, but yesterday there was extreme weather with heavy winds blowing loads of rain over the cacti, ruining them even more. I think i should just cut off the healthy looking green parts and dry them so i can eat them later?? I'm just a bit worried about consuming a cactus which is partly rotten, i dont want to eat parts of the cacti that look healthy but are maybe also sick. I'm a total newbie with cactus consuming.

It might be but if it’s not soft It could recover. My bridgesii’s sometimes get black spots that are mushy and even ooze black shit and they have recovered fine without doing anything. What kind of climate do you live in?

I have a PC with that has had that on it for a couple years. I'm always concerned about it, but its still alive and growing. Bridgesii can be a little more sensitive, but they might be ok.
I think it has something to do with getting sunburned and being more vulnerable to fungal issues, which is what most of that looks like. Is it more on one side than the other?

Its definately not sunburn, they have been inside with no direct sun at all. The fungus or rot or whatever it is, is on all sides.

Looks like the 2nd to last Pic Cactus in the background is trying to throw roots from the side or am I mistaken? They look stressed but not on their way out as long as they aren't mushy. They look like they are in defense mode. Is there fungus or pests in the soil? If not just let them chill for a few months with proper conditions to recover. If you do have roots popping from off the cactus above the soil line I'd trim them off.

No fungus or pests in soil as far as i can tell. But the brown/white spots look so bad and they are everywhere. I gave them to my friend in early april when they were still in winter sleep and they looked great. So from october till last week they have been inside with little light and my friend overwatered them, so what are these white/brown spots if its not sunburn? It must be rot or fungus, however the cacti are not mushy, so thats the only positive thing right now.

As long as there not mushy id let them be but keep a close eye on them. If it gets worse and starts to go mushy everywhere then id cut the tips off and start over.

Thats the plan yeah, i've been putting them in the sun and whenever rain comes i put them inside quickly. Cool avatar btw, i've been a hendrix fan since childhood, back in the mid 90's i even got a portrait of him tattooed on my arm. Its still there but faded a lot

You're not dealing with a rot per se, but rather with a fungus, most likely phomopsis or, possibly, phoma.
The density of some of the scarring, as well as the zig-zag, Charlie-Brown-shirt band of scarring (indicating that the entire tip was affected before it grew through that problem) suggest that a pest (perhaps thrips?) might be playing a role as well.
If thrips are at play, I'd recommend applying a product with spinosad at night (so it doesn't hurt bees) every couple-few days for a couple of weeks. They have a life cycle that includes laying eggs in soil, so you have to keep at them to get rid of them with a surface treatment.
If mites are the culprit, I unfortunately know nothing of those.
But perhaps that thicker scarring is from sunburn, when you moved the plants back into the sun after they'd been in the shade.
(IMO, these are not indoor plants -- even when growing on a sunny windowsill -- and you'd be much better served keeping them outside.)
To slow down the fungus, a copper soap or a product like BioSafe Disease Control could help quite a bit. A systemic would knock it even further back, but that's kindof a nuclear option. You could also think in terms of isolation, cutting tips, isolating clean pups, for the long term. But fungi are part of these plants' (internal) microbiomes, and it's more a matter of maintaining a healthy equilibrium than it is one of removing the 'pathogens' entirely.

@Me_Roy Thx. I'm a complete newbie with cacti so i have to research all the information you wrote. I do know that it is not sunburn because the white/brown spots and damage happened when my friend put the cacti inside her house in a dark spot for 2 months and watered them. They were completely healthy when i gave them to her.

I support your effort to make the most of these bridgesii. However, in the end, you might just prefer to switch to a more resilient, less touchy species, such as pachanoi or peruvianus.
In their native habitats, all of these plants take plenty of rain (especially in the summer). Water shouldn't be a problem so long as they are in very quickly draining soil. (Pumice, granite, crushed stone all work towards that end.) Some of the most sophisticated growers use a 100% mineral potting medium.
Then there is the matter of nutrients. Ammoniacal nitrogen has a positive charge and sticks to soil. That means that when a plant gets a lot of water, the ammoniacal nitrogen and pretty much only the ammoniacal nitrogen remains, leading to a nutrient imbalance. One way to address this problem is to feed with more nitrate-based nitrogen, which has a negative charge, and therefore washes through the soil more readily. (Organic soils and feeds that rely on bacteria to convert ammonia to nitrate have the same effect and might be the best of all options.) But it's also important to introduce all of the other nutrients that your plants need, so that they're not just sucking up the last bit of ammoniacal nitrogen clinging to the soil. Perhaps foremost among the micro-nutrients -- and so important to trichocereus cactus that it's practically a macro-nutrient -- are calcium and magnesium. Get that cal-mag!!

Should all the other measures fail cut and replant the good parts, lost most of a 10 year old L. Williamsii var caespitosa last winter when the soil didn't dry before winter.
