Never. They're fundamentally different things.
Velocity has a size and a direction. Its size alone, without the direction, is speed.
So speed is one part of velocity, but not all of it, so they can never be the same.
Something like a finger can never be the same as a hand.
All objects do not necessarily travel at the same velocity. The velocity of an object depends on factors such as its mass, the force acting on it, and any external influences like friction. In a vacuum, objects of different masses would fall at the same rate due to gravity acting uniformly on all objects.
False. Not all objects have momentum. Momentum is a property of moving objects and is defined as the product of an object's mass and velocity. Objects at rest do not have momentum.
All objects in motion have a velocity, which is defined as the rate at which an object changes its position. Additionally, they possess kinetic energy, which is the energy associated with their motion.
All objects fall to Earth at the same velocity under gravity because they experience the same acceleration due to gravity, which is 9.8 m/s^2 near the Earth's surface. This means that regardless of their mass, they will accelerate towards the Earth at the same rate, resulting in the same final velocity when they hit the ground.
Average acceleration points in the same direction as the change in velocity over time. If the velocity is increasing, the average acceleration will be in the same direction as the velocity. If the velocity is decreasing, the average acceleration will be in the opposite direction.

Galileo Galilei was the first to explain that heavy and light objects would fall the same way in a vacuum. Keep in mind, objects do not fall with 'velocity,' but with 'acceleration.'
Yes. It is different for different planets etc. Escape velocity on earth is different than escape velocity on Jupiter.

because of the differences in air resistance.
All four balls would have the same kinetic energy since kinetic energy is determined by both the mass and velocity of the object. If all four balls have the same mass and velocity, their kinetic energy would be equal.
Without atmospheric drag, all free falling objects near earth's surface will have the same acceleration. But because of friction with the air (air resistance), the velocity of objects due to that acceleration is limited. The actual velocity is dependent on the surface area of the object relative to its mass. The principle of the parachute is to increase the surface area of a falling object with respect to its mass.
