Black holes suck in everything around it for billions of miles, all of that matter is compressed into something smaller than a tennis ball. If you could calculate its weight, it would way many times the weight of our sun!
"Weight" is problematic when it comes to black holes as weight means the gravitational pull of an object on another. What gravitational source would we use to weigh a black hole?
However, the smallest black hole has about three times the mass of the sun.
Black holes are the most massive things in the universe, as far as anyone knows. Even light cannot escape their gravitational pull.
Yes. And they are so dense that nothing, NOT EVEN LIGHT, can escape.
black holes
A black hole has a much larger mass than a planet. The mass of a black hole, however, is contained in a point that is smaller than some fundamental particles. The event horizon of a typical stellar mass black hole is much smaller than any planet, but the event horizons of supermassive black holes are much larger.
An intermediate-mass black hole is one that has a mass somewhere between 100 and a million solar masses, i.e., larger than the stellar black holes, but smaller than the supermassive black holes. It seems likely that such holes should exist, but the observational evidence is not yet very firm.An intermediate black hole is one whose mass is somewhere between that of a stellar black hole (a few times the mass of the Sun), and that of a supermassive, or galactic, black hole (millions or billions of times the mass of the Sun).
An intermediate-mass black hole is one with a mass significantly greater than the typical stellar-mass black holes, but less than the supermassive black holes such as are found at galactic centers. Their identification remains difficult, and their origins remain in the realm of speculation, although a reasonable theory hints at the likelihood of their formation from accretion of dense stellar clusters... and one possibly is that they are primordial black holes left over from the creation of the universe.
Impossible to answer as it's a measure of mass, and there as black holes with less mass than the Sun and some with more.

The masses of black holes vary greatly. The lowest mass stellar black holes are about 3 times the mass of the sun. The most massive black holes are about 12 billion times the sun's mass.

Yes. Most, of a galaxy's mass is stars and nebulae, not black holes.

Black holes would normally be heavier than the solar system, but they would occupy less space, being extremely dense.
A star that stops producing radiation, with a mass about 2-3 times the mass of our Sun (mass remaining after a possible supernova explosion), or more, can become a black hole. There is also some speculation about miniature black holes ("primordial black holes"), with much less mass than that, which might have formed during the Big Bang, because of the enormous density that existed at that time. However, so far there is no evidence that such black holes actually exist.
They will gradually evaporate, due to Hawking radiation. At the current stage of the Universe, black holes of the mass of a star will acquire mass much, much faster than they evaporate - even if they only absorb the background radiation. In the far, far future, such black holes can slowly evaporate.
It depends on the mass of the black hole. The size of the event horizon is directly proportional to mass. Most black holes are what we call "stellar mass" black holes which range from about 3 times to 30 times the mass of the sun. The event horizon of a 30 solar mass black hole would be about 110 miles in diameter. Earth, by comparison, is just over 7,900 miles in diameter. An intermediate mass black hole about 1,340 times the mass of the sun would have an event horizon about the same size as Earth. Astronomers have detected supermassive black holes up to 12 billion times the mass of the sun. Such a black hole would have an event horizon 44 billion miles across, or about 5 times larger than the orbit of Pluto.
I think white dwarfs. This is because they are much more low mass than black holes. White dwarfs are much more common in the universe than black holes, because we have only discovered a few black holes whereas we are aware of many white dwarfs.
