Yes, friction can be involved, as one of the forces. For example, if I push against this heavy desk in front of mine with a force of 100N, and it doesn't budge, that means there is a contrary force of 100N. That force, of course, is friction.
yes
The force of gravity causes a book to fall, but someone has to push it to the edge of the desk, or off the desk so that the force of gravity is greater than the normal force acting on the book.
Static friction is the friction between two objects that are not moving relative to each other (eg: a desk on the floor not moving), kinetic friction is the friction between two objects that are moving relative to each other (eg: a desk sliding on the floor)
forces acting on the book when it rests in your hands are: gravity, the equal and opposite force exerted by your hand on the book (in opposition to force of gravity). Also, air pressure, but its from all sides so it cancels itself out.
friction forces
Yes - if the sum of the forces is zero.Yes - if the sum of the forces is zero.Yes - if the sum of the forces is zero.Yes - if the sum of the forces is zero.
The forces acting on the bookends will be balanced when the gravitational force acting downward on the books is counteracted by the normal force acting upward from the desk through the bookends. This equilibrium allows the row of books to remain standing up without falling over.

When two completely equal forces are applied at one object or each other from opposite angeles. When this happens the object to which force is applied will not move because the two forces will cancle each other out.In other words, if I push a desk left at 2n and somebody else pushes a desk right at 2n the desk will not move.

Particle board computer desks are cheap for a reason. Go out of your way to get a hardwood computer desk to make sure your desk survives the heavy workload of someone who works from home.

It glass desk will have specific weight restrictions make sure you adhere to them.
