Assume one object has twice the mass of another one. Earth will attract it with twice the force. But it will also have twice as much inertia - i.e., it will take twice as much force for the same acceleration.
That depends on how exact you want to be. It is extremely close to being even, but the strength of gravity does vary by extremely slight amounts at different points on the earth's surface. This, of course, means that the mass of the earth does vary ever so slightly from place to place. You would need extremely sensitive instruments to detect this variation.
air resistance
Without the interference of air or any other force, they should fall at the same speed. All objects accelerate at the same rate regarding their masses. To conclude, If this was made in a vacuum they should fall at the same speed but in different conditions it may have different results due to air resistance.
the earth doesnt fall.
earth's gravity

In vacuum, all masses big and small fall with the same acceleration, and reach the same speed in the same amount of time.
Yes. And objects with different sizes, masses, and weights also fall the same.
Uneven heating of different air masses causes the bottom ones to heat up, rise, cool off, and fall in another location in a cyclic motion.
Objects fall faster to the earth, then compared to the moon, it is due to the different power of gravity on the the earth and moon.
The Earth has different seasons because it orbits around the sun making it further away during different times of the year. Earth has fall as it moves further away from the suns energy.

they fall at the same rate regardless of their mass Maryann Saba

air resistance
if all of the forces affecting the objects are the same, then yes (i.e air resistance to a feather).
More massive objects fall faster than less massive objects.
