Because the table is exerting an upward force on the book exactly equal and opposite to the force of gravity.
yep
The force of your pencil or pen against the desk that your paper is on if you're writing something down. The force of your paper against the desk. The force of your book against the desk. In each case, the desk exerts the identical but opposite force against the object lying on it. If that were not true, the objects would deform the desk, or the desk would form a bump where the objects are lying on it.

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.
Because the table is exerting an upward force on the book exactly equal and opposite to the force of gravity.

yep
yes it can. the reason why is the force the wheels are exerting is pushing them foeward. ok that sucked look read a book dont check internet
Gravitational force (weight), pointing down.Reaction force, equal to the gravitational force (weight), exerted by the tabletop, pointing up.
It depends. Two surfaces which are pressed together will show a frictional force resisting any sliding. If they are pressed together by gravity (e.g. such as for a book lying on a table), then the frictional force resisting a horizontal push will depend on the weight of the book, which depends on the force of gravity.
