I need to know what are the Rules towards Negative Numbers as in which ones are greater than the others?

Think of the number line or the x-axis of a graph with zero at the center. Numbers increase as you move to the right and decrease as you move to the left. -14 is 14 units to the left of zero and -9 is 9 units to the left. Since -14 is further to the left than -9 , -14 is less than -9.
