Are All These Damaged Tires Really Beyond any Possible Repair?
These are all really nice tires that were damaged. I put them aside, thinking someday I would find a way to make them usable again. No I a thinking my hope was misguided. Here are picture of the tires and I wonder whether there is a way to repair at least some of these

All but #6 are repairable, though I'd probably only use them in the rear.
You need cloth reinforced patches (search "tire boots"), applied on the inside oriented on the bias to match the tire's plies.
Then finish with tread filler on the outside.
That's the idea, and there's plenty of info available on thd net to fill in the details.
FWIW I've routinely done similar repairs and many worse then yours. Even tire 6 can be made rideable, but only as an emergency in lieu of walking 25 miles. Generally, I prefer to fix and put back into service at the first opportunity, so they don't accumulate, and I'm only using one at a time.

My rule is I slowly inflate the suspect tire to just about rated pressure and look for any bulges (cut cords) at the damage site or "wiggles" (cord separations) anywhere around the tire. If I discover a cord separation (which can be invisible when deflated), the tire is done, as it will get progressively worse. If there is no bulge at the damage site and the cord damage is minimal, it is noted as fit for service. If there is a bulge, I boot the tire using either commercial boot material or cut-up very thin tire casing (preferably from a failed tubular) and use a flexible filler such as Shoe Goo to fill tread gaps if needed. Two of my active-duty tires are fixed this way and are showing no additional progressive failing at the repair sites.
Sample photo of a cord separation "wiggle" for reference:
The only other type of tire failure that in my experience is not fixable is anything involving a cord separation or split at the tire bead. Even a small cut or tear at the bead seems to quickly become an uncontrollable aneurysm or earth-shattering kaboom. Which is unfortunate when it happens on the road, as it did last year on a 20" tire on my Bike Friday. Even with booting, gaffer's tape, and less than 10 psi, it wouldn't stay together. I had to get a ride home.

All but the last I'd try to use again. Probably by cutting some of the adhesive emergency repair sail tape I still have. But the cloth reinforced tire patches or boots are likely better. If the cut area still bulges out quite a bit then you might be a little wary of it for rides you want to go as perfect as possible. So not for my century ride or regular group rides where others will snub you for holding them up if they failed. But for solo rides or use on another bike, why not?

If the ply is so damaged such that a tube bulges at it, these I toss or cut up to make tire liners (discarded thin road slicks make great liners).
Otherwise if I see a tube doesn't bulge from it, I cement the inside of the tire with a scrap piece of inner tube just so water doesn't enter, and these tires I use all the time for my train station beaters.

I am in shock.
.
Do all the notes posted so far apply to CLINCHER tires?

I don't know why I had such incorrect information. I had the impression from somewhere that repairing tires does not ever work. I have so.e documentation and video on the details of how to do this. All these tires have low milage on them. They were damages by crud that exists all over the large city where I live (Houston, tx)TX.
Thank you for waking me up what can be done.

I have cut up Tyvek envelopes and carried them in my saddle bag for situations where I need an emergency tire boot. I needed them one time, and I was able to go 15 miles back to my car. I have also used Gorilla tape to wrap tools in my bag, but I never used Gorilla tape as a tire boot. I guess that Gorilla tape would also work well as a temporary tire boot.
