contact force
false
The support force on an object is called the normal force because it is a force "normal" to the object. "Normal" in this sense means perpendicular.
The force that will push upwards on an object put in water is called buoyancy. Archimedes discovered and accurately described the specifics of this phenomenon over 2000 years ago, and Archimedes' principle is still used today.
Nope. G is a universal constant that applies to all physical objects on earth. The product of an object's mass (m) and G will result in the object's weight, which is just the gravitational pull on the object (the force of gravity). G has the same unit as acceleration. See Newton's second law of motion.
Reaction Force
reaction force
The first one sets the system of coordinates (inertial). The second one gives connection between the net force and the acceleration. The third one postulates than if a first object applies some force F to a second object. The second object is applying the same force F to the first object.

false
The affect of force on the object during collision is described by a quantity called momentum. It is defined as p = mv where = p is momentum, m = mass of the object and v is velocity.
The "force" exerted by gravity on an object (normally called weight) is dependent on the mass of the object and so is different for every object. Gravitational acceleration on Earth is 32.2 feet per second per second.

applied force
A force that causes an object to move in a circle is a central force, or a centripetal force.

That is called the object's weight.
