The opening in the hex screw that holds the rear brake cable has become much looser than it used to be. What is the name of the part so I can order another one? (Hopefully they have some made of harder steel.)

It is simply a clamp bolt and the question is whether it holds the
brake cable tightly when it is tightened, If it does than I shouldn't
worry about it.
As the bolt should be clamping the cable between a flange or washer on
the bolt and the brake arm itself. When it is tightened it shouldn't
move at all.
Your picture looks a bit strange, but maybe it is the perspective. See

from a slightly different angle.

If that clamp bolt gets enlarged much more so my hex wrench slips, it will definitely be a big problem.
How will the bolt become enlarged so that the wrench slips?That seems
to be a contradiction in terms?
Perhaps some more photos would be helpful.
Ah, I think I have it. Your "Allen" wrench doesn't fit well and is
enlarging the internal wrenching head of the bolt. Not much you can do
about that except get a new bolt and the correct size wench.
In the interim have a look at

I've seen a LOT of hex-key head bolts that the hex socket was basically stripped on so that even a proper size hex key no longer worked on it. That can happen if a substandard quality bolt has too much torque applied to it or if the wrong size hex key is used.
AK has said that he used a U.S. Standard hex key on this bolt and that the head of it is NEARLY stripped to the point where he won't be able to tighten or loosen it.
Again, his best bet is to take the bike to a bike shop so that he can get a new undamaged bolt and also the proper size hex key to use on it.
