I have some old lenses from Canon AE1-Program camera. Can I use them for new generation Canon DSLR camera?

Bottom line is, if you are satisfied with the results, that is all that is important.

As I see all the problems of using FD lenses on modern EOS cameras, I would have to say absolutly NO.  You can buy adapters, but these are not a garranty fix.  Notice on your old FD lenses, as you zoom the lens the rear element moves closer to the focusing screen, if it move to far and you snap the shutter there goes your mirror, and shutter assembly.  The fix is not worth the attempt.  It will make a fully functional EOS camera into an instant brick.  Good luck with your endever, hope for success, but be ready for disaster.

I'm surprised that you are the only one to point out the potential damage to the EOS. This something I'll look into carefully.

"Notice on your old FD lenses, as you zoom the lens the rear element moves closer to the focusing screen, ..."

Not likely. I would not say 100% it wouldn't interfere but it won't interfere. The FD/EOS adapter adds distance to the lens. That's why it usually loses infinity focus. I do agree it is a bad idea. though. I've tried them all!  😣
