Freely falling bodies undergo acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. This acceleration causes the speed of the falling object to increase as it falls towards the ground.
The conclusion of freely falling bodies is that all objects fall towards the Earth at the same rate of acceleration, regardless of their mass. This acceleration is approximately 9.81 m/s^2 and is known as the acceleration due to gravity.
No effect whatsoever. Any two freely falling bodies fall with the same acceleration when dropped in the same place on the same planet. That includes any two objects falling on Earth. Someone is sure to jump in here and point out that objects with different mass don't fall with equal accelerations on Earth, and that's because of air resistance. They may even go on to provide answers to other questions that were not asked, such as a treatise on terminal velocity. All of that is true, even if confusing. This question stipulated that the bodies in question are "freely fallling". Bodies that are falling through air are not freely falling.
Some problems with freely falling bodies include air resistance affecting the acceleration and different initial conditions of objects leading to varied outcomes. Solutions can involve ignoring air resistance for simplicity or accounting for it in calculations, as well as using proper equations to calculate the motion accurately based on the initial conditions provided.
A freely falling body, as the name implies, is not hindered in its fall. "Not hindered" is to be understood as not appreciatively hindered for the purposes of describing its motion with a simple equation. A relatively heavy object near the Earth is not hinder for a short trajectory of a few meters. Then, a simple rock or ball or anything, even a person, will move in a straight line or in an arc that is well approximated by a parabola. (The actual path of a freely moving object will be an ellipse, but the short portion you see in a trajectory near Earth is indistinguishable from a parabola.) If you want a purer form of the freely falling object, the best examples are bodies outside the Earth's atmosphere, for example, satellites that go around the Earth. These circular orbits are simplified versions of an ellipse. For extra credit, explain how a geostationary satellite, which appears to remain at the same point in the sky above the equator, is actually moving in an ellipse.

Why the velocities of falling bodies are not proportional to their weights?
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
