Yes. For a start, gravity pulls it down. Also, the table pushes up on the book, thus canceling the force of gravity.
Yes, the force due to gravity which is equal to the weight of the book.
Yes there are: the force of the earth's gravity and the resistance of the table.
As long as the book's velocity changes, there is a net forces acting on it - in other words, the forces are unbalanced. By the way ... How exactly does a book that is resting on a table slow down and come to a stop ?
All of the forces together balance out. The resultant of the forces is therefore nil. That applies to all equilibrium.
Relative to the table, the book remains stationary because there are no outside forces acting on it except gravity which keeps it lying on the table.
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.

Yes, there are forces acting on both the pen and the book. When the pen is placed on the book, the force of gravity is acting on both objects, pulling them downwards. Additionally, there may be contact forces between the pen and the book depending on how they are positioned.

The book will not fall to the ground because of the force of gravity pulling it down and the normal force exerted by the table pushing it up. These two forces are equal and opposite, resulting in a balanced system where the book remains stationary.

book motion
The forces are unbalanced. The force of Friction is obviously greater than whatever force is pushing the book in the direction of travel, if one is pushing it at all. If the forces on the book were balanced, the book would continue to slide with a constant velocity.
No. There may be forces on the body but they are balanced so that the net force is zero. For example a plate on a table is not accelerating but there is a gravity force towards the earth and the table creates a balancing force. Thus the plate just sets there not accelerating. This Newton's Third Law in action.

For example, if the book is resting on a table, gravity pulls the book down, and the table pushes the book up.
