Can oak stair rails and spindles be removed?, are these screwed in?
Any tips/tricks on removing them without damaging them since they need
to be put back.

If they are built so the spindles must be cut at the treads to remove
them, what technique to use to reattach them?

This is a tedious job. They may be mortised, doweled, nailed or
screwed. If you cut them, they are (obviously) damaged. Hot vinegar
will loosen most wood glues. Working on a staircase is experienced
or advanced-level woodworking. To reattach them use traditional
joinery techniques rather than nails or screws. Good luck.
