The energy that radiates from a star originates in the nuclear fusion process going
on in its core. That process continues as long as there is hydrogen remaining to be
fused. When the star runs out of hydrogen, its energy output changes, and eventually
diminishes to a trickle.
In the case of our Sun, it's estimated that perhaps half of the Sun's hydrogen has
been fused, meaning that the Sun is perhaps halfway through its lifetime, and may
change drastically in only another 4.5 billion years.
Two stars orbiting each other are "binary stars" ...a group of stars near each other, may be formally or informally known as a "cluster".
Planets orbit stars.
Population II stars are the oldest in our Milky Way. Population III stars were the first stars in the Universe, but have yet to be discovered. See related question
Maybe from all stars, thousands of stars, in the galaxy.
Roughly half of all stars in the galaxy are estimated to be part of binary or multiple star systems. This means approximately 50% of stars are binary stars.

Put in Star signs. There's PISCES (stars), VIRGO (stars), ARIES (stars), CANCER (stars), SAGITTARIUS (stars), LIBRA (stars), GEMINI (stars), LEO (stars), SCORPIO (stars), CAPRICORN (stars), AQUARIUS (stars), and TAURUS (stars). I think that's all the Star signs. Good luck!
Shooting stars are not stars. They are bits of dirt and dust that burn up in our atmosphere, briefly making them look like stars. Most of that is debris is from comets or others bits of dirt in space, but they are not stars and were not stars. So stars do not become shooting stars.
