It is contact force
The "field" transmits a change of environment that exerts a force on the remote object.
None. Change your question for two OBJECTS and the answer is friction.
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.

A magnetic force.
they must be touching

Force of gravity and natural force act on an object without touching it. <><><> Besides gravity, magnetism, and radiation, such as infrared light.
A force that causes an object to move in a circle is a central force, or a centripetal force.
The buoyant force is zero when the object is just touching the liquid. As the object displaces more volume, the buoyant force increases until the object is completely submerged. Once the object is submerged, it doesn't matter how deep it is, the buoyant force remains constant.
