Let me ask you a question.
If I shot a bullet straight up, and then dropped a feather.. would the falling object move faster than the one going upwards?

This is because the velocity of the moving objects increase with time in relation to the gravitational pull.
the reason why it increases is because the force acting on it is pulling it downwards. if it were pulled upwards then the inverse would apply. Also as the object moves upwards it experiences resistance caused by the air molecues(but it is not the main reason as to why it moves slowly), But also it experiences resistance caused by the gravitational pull that is acting in the opposite direction to the objects movement thus the reason to slower speed.
If the object is traveling downwards then the speed is incerased due to the fact that the force acting on it is pulling the object in the same direction as the movement of the object thus the incerase in speed.
Remember an object moving upward will need more energy compared to an object moving downward at the same speed.

Probably because falling objects are being pulled by gravity downwards and so there is force from that.
Objects that are moving upwards are actually working against the force of gravity and that slows them down.

falling objects are being attracted to the earth by gravitational pull thus causing to move faster
objects trying to go upward are fighting against the force of gravity and thus can not gather speed at a rapid or even even rate.

They DON'T!!!
A falling object will start at a 0 velocity and increase its speed according to v = g.t. After 5 seconds fall, it will reach a velocity of v = 10 * 5 = 50m/s.
If you throw an object upwards with an initial velocity of 50m/s, it will reach zero velocity after exatly the same 5 seconds!
(This is neglecting the air resistance).
Taking air resistance into account, there are differences. Check "Terminal velocity" at wikipedia.

object going upward are infact trying to break free from the gravitational pull of the earth hence they tend to move slower than the objects falling down. ( the law of attraction and repulsion applies here)

because the grvitational force acts downwards and not upwards

because of gravity
