the normal force
If that force is not perpendicular to the surface, then there is a component of the force that's parallel to the surface. That component would move fluid around, until there were no longer any force parallel to the surface ... and the whole force would again be perpendicular to the surface.
Reaction force.
Perpendicular Force is the forces that acts at right angle to the object.
In physics, there is a force that is called the normal force. This is the force that comes from a surface pushing up on an object. If the surface is level, the normal force is the exact same magnitude as the gravitational force, but straight up. The normal force is always perpendicular to a surface. Hope this helps!
Lift is the force that acts upwards, perpendicular to the chord of the wing. Thrust is the force acting perpendicular to the propeller disc.
No, because the force is perpendicular to the movement.
The normal force acts perpendicular to a body and in the downward direction.

Contact Force
In physics, a contact force is a force that acts at the point of contact between two objects A contact force is a force applied to a body by another body that is in contact with it.
