Please show the formulas that he used in calculating the mass of each of the planet. Thank you for your support this is my assignment in Physics.

did he?
he talked about attraction force (F) between bodies (m1, m2, staying d distance apart) though
F = G (m1. m2) / d^2

It wasn't until Henry Cavendish determined the universal gravitational constant, G, that the masses of the heavenly bodies, or the earth, could be calculated.
He did this by using Newton's Law of Universal Gravitation for the attraction between lead spheres of known mass and separation.

Newton needed to use Kepler's 3rd law, which is that the ratio of the square of a planet's (or moon's) to the cube of the semi-major of the axis of its orbit is a constant. For the planets, observation of the orbit times of the moon would be required to compute its mass, once the mass of the Earth is already known.
