Depending on the situation, acceleration can be any of those.
Acceleration is any change in velocity. Velocity is made up of a magnitude (the speed), and a direction. Velocity can change if the speed increases, if it decreases, or if the direction changes. For example, when a car goes around a curve, you feel the force of the acceleration.
If your acceleration is increasing then by default your velocity has to increase. Acceleration = velocity/time so if acceleration is increasing the velocity is also increasing... And just for fun, just as the change in distance is velocity, and change in velocity is acceleration with respect to time, the change in acceleration with respect to Time is called a jerk
If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.
No, increasing mass does not increase acceleration. Acceleration is dependent on the force applied to an object and the object's mass. In the equation F = ma, where F is the force, m is the mass, and a is the acceleration, increasing mass would actually decrease acceleration if the force remains constant.
The answer depends on what variables are being plotted.
No. Acceleration is proportional to the applied force.

-- constant acceleration -- speed increasing at a steady rate -- distance increasing as the square of the time since everything started
No. Acceleration IS a change of velocity - any change. When velocity increases, there IS acceleration. The acceleration itself may be increasing, decreasing, or remain constant.
If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.

An object experiencing a constant velocity has zero acceleration. This is because acceleration is defined as the rate of change of velocity over time. When velocity is constant, there is no change in velocity, leading to zero acceleration.
The answer depends on what variables are being plotted.
If the constant acceleration is positive, the graph would be an exponential (x2) graph. If there is constant acceleration, then velocity is always increasing, making the position change at an ever increasing rate.
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
