Or upgrade.

I wouldn't use the term "new installation", unless it's a completely new
installation of Cygwin.
But, yes. Reinstall will perform uninstall of the selected package, including
removal of specified files and execution of relevant scripts, then install it
again. Again, executing all relevant scripts in process.

Generally speaking, yes.
Though, if I were you, I would never touch the top-level spinner. We've been
there already, and we've seen the results.

Yes.
Though, if you're curious (or thorough. Or both.), you may spin the list view
to "Pending" and confirm the real list of packages and their versions to be
installed.
