Contact force acts through direct physical contact between objects, such as friction or normal force, while field force acts at a distance without direct contact, such as gravitational or electrical forces. Contact forces require objects to be in physical contact, while field forces can act between objects even if they are not touching.

A contact force requires physical contact between objects to exert a force, such as friction or tension in a rope. In contrast, a field force acts at a distance without direct contact, such as gravity or electromagnetic forces.
A sound field, an electrical field, a magnetic field, and a gravity field would all be examples of non-contact forces. But though their effects are 'non-contact' their presence may nevertheless be easily detected.
Pushing a door involves a contact force, as the force is exerted by making physical contact with the door. This force is transmitted through the points of contact between the person and the door.
Buoyancy is a contact force that acts on an object submerged in a fluid. It arises from the pressure difference between the top and bottom of an object.

Contact force means that objects need to be in contact for there to be a force. "Action at a distance" means the objects do NOT need to touch one another directly.
A reaction is not a separate force; it is a force that occurs as a response to an action. In the context of contact forces, a reaction force is the force exerted by an object in response to a force acting on it. It is a contact force that arises due to the physical interaction between two objects.
The buoyant force is a contact force, exerted by contact with a liquid that displaces the liquid within a gravity field. No contact, no force.
The electric field is a force field that surrounds electric charges and exerts a force on other charges, while the magnetic field is a force field that surrounds magnets and moving electric charges, exerting a force on other magnets or moving charges.
