The forces of gravity between every two objects attract the objects
toward each other. So I guess you'd call that a 'pulling force'.

Gravity is a pulling force that exists between objects with mass. It causes objects to be attracted to each other and is responsible for keeping planets in orbit around the sun and objects on Earth's surface.
The force pushing up is called the normal force. It is exerted upwards by a surface to support an object placed on it and counteract the force of gravity pulling the object downwards.
When gravity is pulling you downward when you sit, this is a balanced force. The force of gravity pulling you downward is balanced by the normal force exerted by the chair pushing back up against you.
The force pulling the apple down (gravity) is equal in size to the force pushing it up (normal force) when the apple is at rest or moving at a constant velocity. This is because the apple is in equilibrium and the forces are balanced.
Thrust is a pushing force. It is the force that propels an object forward in the direction it is moving.
The equal and opposite force to the downward force of gravity pulling on a man standing on the beach is the normal force exerted by the ground pushing back up on the man. This normal force prevents the man from sinking into the ground due to the force of gravity.
