What is more common in our galaxy white dwarfs or stellar mass black holes?
There are more white dwarfs. Only the most massive stars can form black holes. White dwarfs form from low to medium mass stars, which far outnumber the supermassive ones.
Why have no white dwarfs cooled to form black dwarfs in the galaxy?
According to astronomers and authors Jonathan Weiner and Carl Sagan, white dwarfs - which have been an accepted entities by all astronomers for decades - require an amount of time to "cool down" that well exceeds the current age of the universe - hence there hasn't been enough time for any of them to cool down yet and become "black dwarfs".
Does the supermassive blackhole at the center of your galaxy contain most of the mass of the galaxy?
No. The super massive black hole at the center of the galaxy has about 4 million times the mass of the sun while the galaxy as a whole has at leas 1 trillion solar masses. In other words the black hole at the center of the galaxy accounts for about one twenty-fifth of one percent of the galaxy's mass.
Is the galaxy larger than the sun?
A Galaxy isn't just one object, it is a group of millions of objects, in this case the objects being stars (which are all like the Sun since the Sun in itself is a star). A galaxy is a massive, gravitationally bound system that consists of stars, stellar remnants and an interstellar medium of gas and dust. Typical galaxies range from dwarfs with as few as ten million (107) stars up to giants with one trillion (1012) stars, all orbiting the galaxy's center of mass. Our own Galaxy in which our solar system is found is called the Milky Way and it is estimated to contain at least 200 billion stars and possibly up to 400 billion stars. So to answer your question:Yes, the galaxy is bigger than the Sun.

Which stars are most common in the Milky Way Galaxy Why don't you see many of them in H-R diagrams?
The most common stars are Red Dwarfs. It is probable that up to 80% of all stars in the universe are red dwarfs. They are not visible on the on the H-R Diagram because they are hard to observe from Earth due to their low-luminosity. In contrast O-type and B-type supergiants are extremely rare. The reason for this is because they evolve and die quickly.
