Select all the red and press shift+N to recalculate normals outside.

Or, just Select everything and then re-calculate Normals. So that is: A, SHIFT+N.

That is normal blender behavior, you just got to keep correcting the normals and check every now and then.

Circles are notorious for giving flipped normals,

This is because there is no face when you add the circle, only vertices and edges…

It depends in which direction you extrude on what direction your normals will face.

If for example you extrude in the positive or negative Z direction

Positive Z direction…

And Negative Z direction…
