What is the acceleration on a projectile as it comes down?
32 feet per second per second.
What is the vertical acceleration of a projectile if the vertical component of its velocity vector is zero?
The vertical component of a projectile's velocity is irrelevant. It can be up, down, or zero, makes no difference. As long as projectile motion lasts ... gravity is the only force on the object and you're ignoring air resistance ... its acceleration is constant, and is equal to the acceleration of gravity: 9.8 meters per second2 pointing down.
Does the acceleration of the object change while it is in flight?
Since the velocity of an object is composed of its speed and its direction, then an object under the influence of Earth's gravity will always be changing velocity. If it is near the surface, its speed is slowing down if it is moving vertically up, or speeding up if it is moving vertically down. If it is moving horizontally, its speed is slowing because of air friction. But even when it is in a circular orbit and its speed is not changing, the direction in which it is moving is constantly changing. so its velocity is constantly changing. Since we have no information on what the flight is, there is no useful answer.
At what angle from a horizontal should a weapon be fired to achieve minimum distance traveled by the projectile?
Do you really mean minimum distance? This would be achieved if the projectile went straight up and down, ie 90 deg from horizontal. Maximum distance would be obtained at 45 deg to horizontal.
A vertically launched object When is the acceleration due to gravity greater when ascending from the top or descending?
As long as the object stays somewhere near the surface of the earth, the acceleration due to gravity is constant, whether the object is moving up, down, sideways, or not moving at all.

Could a bullet be fired from one rifle down the barrle of another?
It has happened. During the American Civil War, a Union rifleman fired his rifle, and the projectile collided with the projectile fired by a Confederate rifleman - in the barrel of the Confederate's rifle. IIRC, that rifle was displayed in the Museum of American History.
Is the acceleration due to gravity always pointing vertically downward even for an object whose velocity is vertically upward?
Acceleration only depends on the direction of the applied force and is independent of the velocity of the object, so gravity is always pointing down.
How do you find the launch velocity of a projectile that was fired straight up and came back down to the level it was launched at in 1.37 seconds?
the velocity at the start is the same as when it comes back down to the level. At the top velocity is zero and at the bottom the velocity is acceleration x time where time is 1.37/2 = 0.685s. Acceleration is that of gravity or 9.8 m/s/s, so projectile velocity is 9.8 x .685 = 6.7 m/s; in US system that is 22 ft/sec or 15 mph

What pulls down a projectile motion?
Gravity would be pulling down on a projectile object.
Who will reach first a man coming vertically down or horizontally down why?
vertically is up and down horizontally is side to side. vertically would be first
If a ball is thrown vertically upwards and the acceleration on it is neg 9.8 due to gravity will the sign change when the ball changes direction to fall back down thus giving an acceleration of 9.8?
Yes. On the way up, negative acceleration is taking place because the ball is moving up and gravity is acting in the opposite direction. On the way back down, acceleration is positive, and the object starts at rest.

Is up and down horizontal?
Forward and backwards, right and left can be horizontal movements. The ocean waves moves horizontally. Up and down are vertical movements. A rocket that's been recently fired moves vertically. So the answer to your question is no.
