No, because they are not. Sirius A and B are just two stars in a Galaxy of many billions of stars. Sirius is a few hundred million years old, younger than most of the stars in the Milky Way.
Sirius is actually a binary star: Sirius A, which is a white main-sequence star and which is accompanied by Sirius B, a white dwarf.Around 100 years ago it was suggested that Sirius may belong to the Ursa Major moving group. However, more recent analysis of the motion of the stars in this group, and particularly Sirius's age, ha cast doubt on that suggestion. It is now believed that Sirius may be part of the Sirius Supercluster.
No. There is no such thing a a cold star. Sirius consists of two stars, both of which are hotter than the average star.
From Wikipedia: "The age of the system [Sirius is a double star] is estimated at around 230 million years." So, a fairly young star, at least if compared to typical stars, including our own Sun.
Sirius, which consists of both Sirius A and Sirius B is in the constellation Canis Major, which, if you are looking south, appears below and to the left of Orion. Sirius B itself is too dim to be seen from Earth; the vast majority of the light from Sirius is from Sirius A. Even then, as a binary system, the two stars are too close together for us to see them separately.
Yes. Sirius actually consists of two stars. The main object, Sirius A is not only bigger than Earth but is almost twice the diameter of the sun. The secondary star, Sirius B is a collapsed remnant of a star called a white dwarf. It is slightly smaller than Earth but far denser.
Yes. As with all the stars you see in the sky, Sirius is part of the Milky Way.
Neither. The Sun only appears bright because it is close. Sirius is far larger and brighter than our Sun. Our Sun is probably in the top 40% of all stars in the Milky Way, while Sirius is probably in the top 5%. But there are many other stars that are far brighter even that Sirius.
Method of energy conversion: Both stars fuse Hydrogen into Helium. Location: Both stars are neighbors in the Milky Way galaxy.
Find Orion's Belt, and follow its line of stars down to the left and you will find Sirius. It is unmistakeable. It is easily visible in the winter but not summer. Altenatively, look for the brightest thing other than the moon, and you've found it.
Yes it is. All the stars that we can see are in the Milky Way galaxy. Stars in other galaxies are too far away from us to be able to see them properly. That is even true of many stars in the Milky Way Galaxy.
No too sure what you mean by "main" stars but the most obvious ones are:- * The Sun * Polaris * Rigel * Betelgeuse * Sirius * Vega * VY Canis Majoris * Antares * Alpha Centauri * Barnard's Star
Assuming you just need random examples: the Sun, Rigel, Betelgeux, Sirius, Castor, Pollux, Polaris, Saiph, Alnitak, Mizar, Deneb, Mintaka, Aldebaran, etc.

No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,
Ah, friend, the brightest star in our magical Milky Way galaxy is called Sirius. Just like how every brushstroke adds beauty to a painting, Sirius shines beautifully in our night sky, a true masterpiece of the universe. Just take a moment to gaze up at the sky and feel the wonder of our dazzling cosmic home.
The Milky Way is a huge group of stars, somewhere between 200 and 400 billion stars. The stars themselves, or the Milky Way in its entirety, is not in line with anything.
