Some of the energy is lost (dissipated) in the process of rebounding. Also, air resistance can slow down the ball a bit.
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.
When a ball bounces, it loses some energy as heat and sound due to impact and friction with the surface it bounces on. This loss of energy reduces its ability to reach the same height in subsequent bounces. Additionally, the ball may deform slightly upon impact, which can also reduce its elasticity and ability to return to its original height.
After each bounce, the ball reaches half of the height from which it was dropped. Since the ball was initially dropped from 10 feet, on the first bounce it will reach 5 feet, on the second bounce it will reach 2.5 feet, on the third bounce it will reach 1.25 feet, and on the fourth bounce it will reach 0.625 feet.
Objects of different masses will reach the ground at the same time when dropped from the same height because they are subject to gravity, which accelerates all objects at the same rate regardless of their mass. This is known as the equivalence principle and was famously demonstrated by Galileo.
The key factor in determining the time it takes for objects to fall is the acceleration due to gravity, which is the same for all objects regardless of their mass or material composition. Therefore, both the aluminum and steel balls experience the same acceleration and reach the ground at the same time when dropped from the same height.

The formula for calculating reach using a stack and reach calculator is: Reach Height x 0.53.
If the objects are dropped at the same height in the same time, they will both experience the same acceleration due to gravity. This means they will have the same vertical velocity at any given time during the fall, and therefore both objects will reach the ground at the same time. This is assuming there are no other factors, such as air resistance, that would affect their fall.
An egg would typically reach terminal velocity in about 12 to 15 seconds when dropped from a significant height. Terminal velocity is the point at which the force of gravity on the egg is equal to the force of air resistance, causing the egg to no longer accelerate.
