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.
Speed
All objects do not travel at the same velocity. As an example, you should take a few minutes and think about an earthworm and a jet airliner.
all objects have a terminal velocity once youu reach terminal velocity you can not fall any faster
because of the differences in air resistance.
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.
Yes. Neglecting the effects of air resistance, ALL objects fall with the same acceleration near the surface of the earth, meaning that any two objects dropped at the same time will have the same velocity after the same time interval.

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.

The acceleration is the same for all objects, as long as air resistance is insignificant. After a while, different objects will have different amount of air resistance. Also, even without air resistance, the speed depends not only on the acceleration, but also on how how long the objects are falling.

If several objects have the same speed and the same velocity,then each has the same kinetic energy.
