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.
Astronomers believe that Pluto formed from the same material as other planets in the solar system, but its small size and location in the Kuiper Belt differentiate it from the eight major planets. Some theories suggest that Pluto may have been a moon of Neptune that was knocked out of orbit, while others propose that it formed independently like other planets but was not able to grow larger due to its location.
No. Most follow the new IAU definition of a planet which excludes Pluto.
because of the Hubble telescope pictures.
It was not so much a discovery that Pluto wasn't a planet, so much as a general concensus that it shouldn't be called a planet anymore. Over the past decade, astronomers have discovered several bodies beyond the orbit of Pluto that are in fact larger (for example, Eris.) They realized that there were probably many more they hadn't discovered yet and that the term planet was impractical for Pluto since it was so small and there were so many similar sized objects orbiting the Solar System. Eris was probably the final blow to Pluto's status. It is larger than Pluto and for a long time astronomers called it the solar system's "tenth planet''. In the face of this discovery and the fact that many other similarly sized objects had been found, the International Astronomical Union decided to formally define the word "planet" for the first time in 2006 and in the process effectively demoted Pluto.
Astronomers think Pluto is a dwarf planet. And they're right.

No. There are almost no astronomers that think Pluto is a planet. They know it's officially a dwarf planet.

They don't. Charon is generally considered a moon of Pluto, however, since Charon and Pluto orbit a center of mass that is outside of Pluto some have suggested calling the Pluto-Charon system a binary or double planet.

Astronomers have decided that Pluto does not meet the definition of a planet.
Astronomers now realize that Pluto does not have nearly enough mass to noticeably affect the orbits of Uranus or Neptune.

Pluto is too cold to be a planet Pluto is made completely out of ice
No. Most follow the new IAU definition of a planet which excludes Pluto.
astronomers have discovered 3, of which Charon is the biggest
