I have recently purchased a house and due to some slight settling on the
foundation...

My front door and a couple interior doors are no longer square.

The Front door has distanced itself from the vertical side opposite the
hinges, with the top being flush and the bottom having at least a 1/2 gap.

What does the gap look like along the top of the door, and along the
bottom?

If it's a "square" issue, you should have a 1/4" gap at the top on the
non-hinge side. Also, the bottom non-hinge corner should be scraping
the frame, or nearly so.
