Mass and gravity are directly connected, and luminosity is closely related to mass.

Yes, spectral type, surface temperature, and color are related descriptors of a star's characteristics. Spectral type categorizes stars based on their surface temperature and characteristics of their spectra, with each type corresponding to a specific temperature range and color. So, they all provide insights into a star's surface temperature and related properties.
All stars are sun or sun is the star both are same.
An eclipsing binary is a system of two stars that orbit each other in such a way that they periodically pass in front of each other from our perspective on Earth, causing their combined brightness to fluctuate. By measuring these fluctuations, astronomers can determine properties of the stars, such as their sizes, masses, and orbital characteristics.
The sun is considered a main sequence star on the Hertzsprung-Russell diagram.
Two stars orbiting each other so that one regularly passes in front of the other blocking out some or all of light of the hidden star. See related link for an animation.
First it's Jango Fett. And Rex is not related to Jango because Rex is Jango's clone. So they probably never knew each other though.
A binary star system is two stars that orbit around each other
No no no
Yes
I suggest you look up each of the stars - for example on Wikipedia - and decide what characteristics you want to concentrate on. Two different stars may be different in the following characteristics: mass; diameter; color; surface temperature; distance from Earth; apparent brightness; absolute brightness; and several others.
The term "eclipsing binaries" is appropriate because these binary star systems pass in front of each other during their orbits, causing eclipses where each star blocks the light of the other. This phenomenon allows astronomers to study the binary system's properties, such as their masses, sizes, and orbital characteristics, by observing changes in brightness during eclipses.
