because of the differences in air resistance.
All objects fall to Earth at the same velocity under gravity because they experience the same acceleration due to gravity, which is 9.8 m/s^2 near the Earth's surface. This means that regardless of their mass, they will accelerate towards the Earth at the same rate, resulting in the same final velocity when they hit the ground.
Acceleration due to gravity is due to the force of gravitation exerted on a body by the earth. All bodies get attracted towards the centre of the earth. So the acceleration is always pointed vertically downwards.
If there's any difference, it's the result of air. If you pump all the air out of a long tube and then drop things in it, they fall with the same acceleration, and they hit the bottom at the same time with the same velocity. Doesn't matter if you use a feather, a sheet of paper, a leaf from a maple tree, or a rock.
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.

Yes, the acceleration due to gravity always points vertically downward, regardless of the direction of an object's velocity. This is because gravity is a force that attracts objects towards the center of the Earth.

The velocity in the x direction would be constant because gravity only affects the vertical components of objects. The velocity in the y direction would increase due to the constant acceleration due to gravity. The acceleration due to gravity on Earth is always -9.81 m/s^2.

Only until they hit the ground or the floor.
