No. There are no protons and neutrons on a BH. It is a singularity. Zero
volume, infinite density.

hahaha

Start with neutronium, then add sufficient pressure that even
that volume can't be sustained. There is no force to prevent
the volume from collapsing to zero. How would *you* describe
that state?

Where did it get its spin?

From the spinning star that collapsed. Conservation of angular momentum.

Which star was that?

From the star that contained the mass before it collapsed into
a black hole.

Is there a *preferred* star that collapses and then
becomes the central BH of each galaxy?

No, but where there is a black hole, there used to be a collection
of hot, ordinary matter called a "star".
