No planets have been officially recognised outside our galaxy, though more than 500 exoplanets have been identified outside our solar system. Our nearest galaxy is too far away to detect such planets, though we can assume that it will contain several millions of planets based on observations within our own galaxy.
First and recently are mutually exclusive and cannot be answered
I forgot her name but she is from a planet outside our galaxy.
As of my last update, astronomers have not discovered a new planet in our solar system. However, new exoplanets outside our solar system are routinely being discovered using various observational techniques.
Astronomers have decided that Pluto does not meet the definition of a planet.
Astronomers think Pluto is a dwarf planet. And they're right.
Astronomers once believed that planets were probably rare and unusual, and that tere might not be very many planets. However, recent discoveries indicate that planets are far more common; in fact, almost every star that astronomers have closely observed is discovered to have some planets! So it is likely that the "furthest planet in our galaxy" is on the other side of the galaxy from the Earth. The Milky Way galaxy has a radius of about 40,000 light years, and our solar system is about 3/4 of the way out from the center. So the "furthest planet in our galaxy" is probably somewhere near 70,000 light years away.

The galaxy is not a planet. The galaxy is MADE of millions and millions of stars and planets.
No, not all astronomers consider Pluto a planet. Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union, leading to debate among scientists about its classification. Some astronomers argue that Pluto does not meet all the criteria to be considered a full planet.

No. There are almost no astronomers that think Pluto is a planet. They know it's officially a dwarf planet.
It is not currently known whether there is ANY life, ANYWHERE outside of planet Earth.
