The force exerted by air in all directions is called air pressure. It is caused by the collisions of air molecules with surfaces. Air pressure is exerted equally in all directions and decreases as altitude increases.
The air pressure is exerted in the direction of the air flow. But this is subjected to the Boyle's law. So Boyle's law is correct. You have add the force exerted by the speed of the air to it.
In all directions.
Air pressure is exerted in all directions.
The force in an inflated balloon is exerted outward equally in all directions.

Yes, force is a vector quantity, because it is exerted in a specific direction (even in the case of a symmetrical explosion, in which force is exerted in all directions, that is still a type of vector).
All directions, just like water when you are diving. That is why chocolate-covered cream cakes (and a lot of other stuff) stay together at atmospheric air pressures, but will explode in vacuum, or why water will boil at lower temperatures on high mountains.
Because the pressure is exerted throughout the body of water.
Air pressure is the force exerted by the gases in the atmosphere as Earth's gravity pulls on it. The atmosphere can be thought of as a 'sea' of gas surrounding the planet. Air pushes against us from all directions as the weight of air above compresses the air below (this is why altitude affects air pressure.)
All three of the forces are acting on the office chair.
gravitational force
No. Quite on the contrary: Air provides a buoyant force, that will partially counteract the force of gravity. And if the object has a low density (as in a balloon), it may even get the object from the ground.
