No. It is estimated that it would take trillions of years for a white dwarf to cool to a black dwarf. The universe is not old enough for that to have happened yet.
no, dwarf stars don't have enough mass
Some stars become a black hole or a black dwarf.
We don't think there are any black dwarf stars yet. There hasn't been long enough for them to cool to the "black" stage. When there has been, then presumably some of them will have satellites.
It is not old enough. It is estimated that it would take trillions of years for a white dwarf to a black dwarf. The universe is only about 13.8 billion years old.

No in the life cycle of a star, a white dwarf can cool and become a black dwarf
Yes there are a few more [See related link for more information].--- Main sequence stars -----Red dwarf Yellow dwarfBlue dwarf (hypothetical)--- Degenerate stars --------White dwarf Black dwarf (hypothetical)--- Sub stellar stars -------Brown dwarf.
A stars evolution. Our Sun will go yellow dwarf -> red giant -> white dwarf -> black dwarf.

No. That is why they are called black dwarfs. See related question
No, a dead star is different from a black dwarf. A black dwarf is a type of stellar remnant, but not all stars become black dwarfs. When a star dies it will leave behind a white dwarf, a neutron star, or a black dwarf as a remnant depending on its mass. Given enough time a white dwarf will eventually cool to a black dwarf. The universe is not old enough for this cooling to have happened yet.
