When other debris hits them or parts of them break off, some fragments will have lower mass and slightly different trajectory and therefore may change into higher orbit.
Not really. They may go into a higher orbit temporarily, but they would be highly elliptical, repeatedly dipping into the atmosphere and bleeding speed
Those pieces would still have their original low periapsis and deorbit pretty quick. Kessler syndrome isn’t about very low orbits where drag is significant

And simply due to physics, those will be the exception and not the rule, and so not enough to cause Kessler Syndrome.
