How to adjust the book stand effectively?

Hold down the middle of the base panel with one hand, grasp the upper support with the other hand, and lift the stand with force.

Can I lubricate or loosen the hinges to make it easier to adjust?

The construction is pretty tight at the junctions so it protects your book from slipping and falling off. Lubrication may make the stand wobbly.

Does it swivel both ways? Can the base swivel be locked if I want it to stay in a fixed position?

It swivels both ways. You cannot lock it, but the base won't rotate without considerable effort.
