The gravitational constant is usually an uppercase G, sometimes called "Big G". It's value is approximately 6.67x10e-11. This doesn't change. That's why it's called a constant.
The acceleration of gravity at the surface of the Earth is usually a lowercase g, or "little g." This value is around 9.8 m/s^2, but this can vary quite a bit depending on your altitude and variations in the Earth's crust.

True and false. g usually measures the gravitation between celestial bodies where local variations can be disregarded. But g is not a constant when gravitational measurements are made close to the surface of Earth (or any other body).

True but the gravity isn't constant along the Earths crust.

True. But they do affect the acceleration due to gravity.

Depends ...do you mean the gravitational constant G ....or the acceleration due to gravity , g.?
