Years ago (50?) I used to use a ring to reverse my lens on the camera for macro. Going through some boxes in the closet I came across a couple. How different would it be using these rings on a DSLR

On the old Canon FD lenses one could lock the aperture and manually adjust it.
I've no idea how one would do that with the current lenses for digital cameras.

You couldn't do it with lenses where the aperture is controlled by electronics only.

If you wanna fuss around, you could set an aperture with the lens mounted normally and then remove the lens BEFORE powering off. Now you have a fixed aperture lens, f/stop as you chose it. Now you can reverse mount it. This works on most cameras but its really more trouble than its worth.

Youre just too fast. Go back and read the finished post. I accidentally sent it before it was complete. Or just take it here and now that you must never reverse any lens that lacks a manual f/stop ring. Period.
Some Hawgsters who cannot understand "Period" will surely have other "advice".
Dont take ANY advice from those parties. Never. Not now, and not ever. Especially ignore their links to products and videos.
PERIOD.

You have the Canon EF lenses so remove one from the camera body and see how which aperture it is set at.
With Nikon the older lenses with aperture ring then you can simply set the aperture with the ring.
With the G lenses which don't have the aperture ring but is controlled via a mechanical level from the camera body the lens is closed to minimum aperture when removed from the body.
With type E lenses which the aperture is controlled by electrical signal from the body the lens opens to maximum aperture when removed from the body.
