a body projected upward is in rest at the top most point, but acceleration is not zero
Yes, a body can have zero velocity and still have acceleration. For example, when a car is at a complete stop but then accelerates to start moving, it has zero velocity at the moment before acceleration kicks in. Another example is when an object reaches the peak of its motion and momentarily stops before accelerating back downwards due to gravity.
When a car is moving forward and the driver suddenly applies the brakes to stop, the car's acceleration is against the direction of motion. This is because the acceleration due to braking acts in the opposite direction of the car's velocity, causing it to slow down.
unbalanced forces cause acceleration, an object in freefall has gravity as an unbalanced force.
To calculate g-force from acceleration, divide the acceleration by the acceleration due to gravity (9.81 m/s2). This will give you the number of g-forces experienced. For example, if the acceleration is 20 m/s2, the g-force would be 20/9.81 2.04 g.
A car increasing its speed from 0 to 60 mph in 10 seconds is an example of acceleration. A ball thrown into the air, moving faster and faster as gravity pulls it downward, is also experiencing acceleration.

When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum
Variable acceleration refers to an object's velocity changing by different amounts over time. This means that the object's speed is not changing at a constant rate. An example of variable acceleration is a car speeding up as it merges onto a highway, where the acceleration is increasing. Another example is a rocket slowing down as it enters the atmosphere due to air resistance, where the acceleration is decreasing.

You can find an object's acceleration by dividing the force acting on it by its mass. The formula is: acceleration = force / mass. This will give you the acceleration of the object in the direction of the force.
No it is not because its direction is constantly changing. It is not a constant force. Force has direction as well as magintude and while it magnitude is constant its direction is not.
To give an object a greater acceleration, you can either apply a greater force on the object or reduce its mass. Increasing the force acting on the object will accelerate it more, while reducing its mass will also result in a greater acceleration for the same force applied.
You ignore the acceleration, and just give them the mass. Now, if they give you the acceleration and the applied force, you could use m = F/a.
