When the elevator suddenly stops, your body tends to remain in motion due to inertia (Newton's First Law). As a result, your blood continues moving downward towards your feet until it catches up with your body's new motionless state. This is why you may feel a momentary sensation of blood rushing from your head to your feet.

You are standing on a scale in an elevator Suddenly you notice your weight decreases What do you conclude?
If my weight decreases while standing on the scale in an elevator, it likely means that the elevator is accelerating downward. This decrease in weight is due to the elevator and myself accelerating at the same rate, creating a sensation of weightlessness.
Why does your blood rush from your head to your feet when you come to a stop in a descending elevator?
Your brain needs a constant amount of blood pumped up to it in order for it to function properly. (If you have a poor blood circulation, you should consult your local doctor). The blood pumped by the heart is sent to different parts of the body through blood vessels called Arteries. One of it's destinations is to your brain (carries oxygen, glucose etc to the cells). In order for the blood to be pumped up to your head the blood needs to be under pressure. When the blood is under pressure it pumps further, which is what is needed for the blood to be pumped up to your brain. The blood does not need to be under pressure when it travels to your feet since it can work together with gravity to reach it. But when the heart wants to pump blood up to your brain, it has to work against gravity which is why pressure is needed. Branchiocauras's have necks that can measure up to 5-8 meters long. The blood pumped by the heart needs to be under a tremendous amount of pressure so that enough blood reaches your brain.

If a boy doing toss in an elevator and elevator suddenly disconnects so what happens with the coin?
I assume you mean, the cables that sustain the elevator break.The coin will maintain its relative movement relative to the elevator. For example, if at the moment the elevator disconnects the coin is moving upward at 1 m/s (with respect to the elevator), it will continue going upward at the same speed (once again, with respect to the elevator), until it hits the ceiling. This is because both the elevator and the coin will accelerate downward at the same rate.
