That is because Earth attracts objects with a certain force (through gravitation). If the gravitational force were more, the acceleration would be more. If the gravitational force were less, the acceleration would also be less.
9.8
The SI units are 'meter' for distance and 'second' for time. 'Acceleration' is a derived unit that uses both of them. it's [ meter/second2 ].
The accepted value of the acceleration of gravity near the surface of the Earth is approximately 9.81 m/s^2.
The acceleration of the ball at that moment would be approximately equal to the acceleration due to gravity, which is about 9.81 m/s^2. This acceleration is acting downward towards the ground, assuming no other forces are acting on the ball.
If gravity is the only force, they WILL have an acceleration of about 9.8 meter per second square, close to Earth's surface. However, there may be forces other than gravity involved - such as air resistance.

No.
by giving the unit as meter per second square.
Because that's how it was found to calculate it.

Acceleration due to gravity is expressed in the same units as any other acceleration ... Meters per second per second = m/s2 Also feet per second per second = ft/sec2 Any unit with dimensions of (length)/(time)2 is a valid unit of acceleration, such as (furlongs)/(fortnight)2
There is no unit of "gravity". Gravity is described in terms of its effects, namely acceleration and force. SI unit of force: [ newton ] = 1 kilogram-meter/second2 SI unit of acceleration: meter/second2

Acceleration has units of speed / time. The standard SI-unit is meter/second/second, usually written as meter/second2. Other units of distance/time/time can also be used, but it is convenient (for equations) to use a set of consistent units.
The acceleration of free fall is 9.8 meters per second squared because of the force of gravity acting on objects near the surface of the Earth. This acceleration is a result of the gravitational pull exerted by the Earth on all objects. It is a constant value that allows for consistent and predictable motion of objects in free fall.
