Scientists measure the weights of planets by observing the gravitational forces they exert on other objects, such as moons or spacecraft. This data, along with Newton's law of universal gravitation, allows scientists to calculate the mass of the planets and, by extension, their weight.

As a rough - not absolute - measure, yes, that is correct
Astronomers measure it by predicting with the stars and using scientific tools
they checked it by checking the position of the planets.
Other than Earth, no planets have been confirmed to be habitable. We do know of planets in other star systems upon which liquid water could theoretically exist but we can't measure the composition of the planets atmospheres therefore we can't know for certain whether or not they are habitable.
Spheres only have one diameter. Planets are a little different than spheres in that they tend to bulge at the equator, so the size of their diameter depends on where you measure it. Planets are usually measured along the equator, but you could measure them in an infinite number of places.
Yes, gravity affects your weight on different planets. Weight is a measure of the gravitational force acting on an object, so on planets with stronger gravity, you would weigh more, and on planets with weaker gravity, you would weigh less compared to your weight on Earth.
because it is the fastest way to measure in very long distances for example earth to other far away planets
