Hmm, all I’ve ever seen is 3/8.Nope, I have 2 different sizes, 1 about 3/8 for the 3 jaw, and 1 about 5/16 for the 4 jaw.

Some use a square socket, allens, all sizes of squares, depends on the chuck.Hmm, all I’ve ever seen is 3/8.
The pieces aren't too long. I order raw materials by the foot, and I usually part them off into thirds before I start creating parts....this way I usually don't need to use the steady rest.How about an expanding mandrel that fits the size of tubing he's machining?
What sort of tolerances are we talking about here?
I gather they're not too long or he'll have trouble parting off.
They don't look large enough to do 1.5" OD tube....what are they called so I can google them and do some homework?Yes, Have a look at these, or better still custom make one for the job at hand. A much safer and efficient option in my view.
how thin is the part your trying to make ? the last thin walled thing I did was a aluminium shim for my bikes seat post.Yes, I have done that. It sorta works.

If it's very thin you might need to core the entire part. This could be like a mandrill that you super glue it onto for working it so you can hold the mandril in the chuck jaws.
