If a ball is rolling in a straight line and you push it to the right velocity will accelerate.
If you push a ball rolling in a straight line to the right, its velocity will change in the direction you pushed it, affecting its speed and direction of motion. The velocity will have a component in the direction you pushed it, as well as any remaining component from its original motion.
This is an example of inertia. The rolling ball has more mass, so it has greater inertia than the ping pong ball. This means it requires more force to stop the rolling ball compared to the ping pong ball at the same velocity.
The velocity of a ball rolling down a hill will increase due to the acceleration caused by the pull of gravity. As the ball gains speed, its velocity will continue to increase until it reaches the bottom of the hill.
Yes, a rolling ball has kinetic energy due to its motion. The amount of kinetic energy it has depends on its mass and velocity.
Not necessarily. If it's rolling in a straight line on a smooth and level floor, then the acceleration is as good as zero. But if the ball is rolling up a hill, or down a hill, or around the groove in a roulette wheel, or through grass and slowing down, then there's substantial acceleration.

The overall velocity would increase. The ball would then have a curved path with some velocity vector in the North South direction and some vector in the East West Direction
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?

This is an example of momentum, which is a product of the object's mass and its velocity. It is also harder to start a bowling ball rolling than a ping-pong ball due to inertia, which is related only to the object's mass.
