No. Currently UY Scuti is the star estimated to be the biggest, but we are not very sure of their size; beside UY Scuti, VY Canis Majoris and a few other stars are also larger than Betelgeuse.
Yes, Betelgeuse is one of the brighter stars in the sky. The red star of Orion's left shoulder is Betelgeuse.
Betelgeuse varies in brightness a bit, but it's around #8 in brightness.
Both Betelgeuse and Pollux are close to the end of their life. Both of the stars are large and cold in surface temperature. One difference is that Betelgeuse is a red supergiant, and Pollux is an orange giant.
Betelgeuse boasts the diameter greater than the orbit of Jupiter. It has a mass of around 20 times the mass of the Sun, and its luminosity is almost 200,000 times greater than the Sun. So really, it is one of the biggest and brightest stars ever observed.
Betelgeuse is one of the larger stars, while Barnard's star is just a little red dwarf star. So, yes- Betelgeuse is far larger than Barnard's.
Betelgeuse is a red giant star in Orion, and it is one of the biggest and brightest stars known.

Yes, it's one of the brighter stars in the night sky.
Many stars are bigger, but Betelgeuse is one of them, a red giant.
I saw it last night. Betelgeuse is one of the brightest stars in the sky, you just need to know where to look and it's easy to see.
Proxima Centauri has an insignificant luminosity to Betelgeuse. Although it is the closest known star(4.2 light-years) to our Sun, it is virtually impossible to see because it is so dim. Betelgeuse, on the other hand, is a lot farther (640 light-years). Yet, it is one of the brightest stars in our night sky. This is because Betelgeuse has an extremely high luminosity.
A Red Giant Stars that are much bigger than the sun are the giants and of course the super giants, which are the stars with the biggest size. If you want a specific one, Betelgeuse or Antares would be good choices.
There are approximately 200 to 400 billion stars in our galaxy. Milky Way is one of the biggest known galaxies.
