The answer is more complicated than a mere 'yes' or 'no'. Dr. Stephen Hawking predicted that black holes emit a certain amount of thermal radiation (this became known as Hawking radiation). According to his predictions, the amount of radiation emitted by a particular black hole is inversely proportional to its mass. If he is correct, it means that there is a critical point where the mass of the black hole results in Hawking radiation emissions of a 'temperature' equal to that of the cosmic microwave background, approximately 2.7K (you can think of this as the temperature of space). Any larger, and even the cosmic microwave background serves to feed the black hole. Any smaller, and it will eventually evaporate.
The exact mass needed for such an occurance (the 'critical mass') is not something that can be easily written down. It varies, somewhat, based on the type of black hole. That said, any black holes of mass equal to, or less than, that of the Moon could generally be expected to evaporate over time.
All of this is speculation, however. Any black hole of sufficient mass to remain stable over time will emit so little radiation that it will be indistinguishable from the cosmic microwave background. Only a short lived black hole could be observed in such a manner, and we have yet to observe any.
Yes, black holes slowly evaporate after meeting critical mass or without any planets or star around it
Probably stellar mass black holes

The most massive stars will die as black holes.
High-mass stars might become black holes, if the remaining matter (after the supernova explosion) is sufficiently large.

The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.

No. Without matter there would be no black hole. The black holes confirmed to exist so far actually have a fairly large amount of matter (or mass) - at least 2-3 times the mass of our Sun. The largest black holes have millions or even billions of times the mass of our Sun.No. Without matter there would be no black hole.

Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
High-mass stars might become black holes, if the remaining matter (after the supernova explosion) is sufficiently large.
In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
there are four types of black holes. 1. super massive 2. Intermediate mass 3. Stellar mass 4. Micro
