UpFrust
The force pushing the object up when it floats in water is called buoyant force. This force is a result of the difference in pressure between the top and bottom of the object in the water, pushing the object upwards.
When an object is falling toward Earth, the force pushing up on the object is gravity, which is pulling the object downward towards the Earth's center. There is no active force pushing the object up as it falls.
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.
The force pushing a parachute up is called drag. It is created when the parachute interacts with the air as it falls, slowing down its descent.
Gravity. A parachute uses the force pushing up on a large area of silk to resist the force of gravity, allowing for a controlled descent and landing.

A surface pushing up, equal and opposite to a force pushing against it
If the object is outside the earth's atmosphere, there is no force pushing up on it. If it is inside the earth's atmosphere, then air drag is pushing up on it.

In physics, there is no special distinction - no special names to distinguish - pushing forces from pulling forces. Of course, you can simply call it "a pushing force", if you want to make such a distinction.

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.
When you throw a ball, you exert a force on it by pushing or propelling it in a direction. This force causes the ball to accelerate and move through the air. In this case, your arm muscles are applying a force to the ball to make it move.
