No. Arcturus is believed to be a single star.
Arcturus is in the latter part of a stars life. It is a red giant and it's mass is too low for it to "go" supernova. More than likely it's demise will be similar to our own Sun.
Hmm. Let's have a look out side. How many Suns do I see? One. Our Solar System is not part of a binary star system, otherwise you'd see two Suns in the sky.

There is no special machine that measures that directly. Astronomers have to observe objects known to be close to the black hole (most black holes observed are part of a binary or multiple system, simply because those are easier to detect), and use one of the usual methods used in astronomy to calculate distances.
No - it is a single star system
No, our Sun is not part of a binary system.
No, as a binary system is two stars, one circling around the other
In order to be part of a binary system there has to be two suns in the system. Our solar system has just one sun, hence we call it the sun.
Part of a binary star system.
Yes all binary stars are part of the star system because all galaxies and universes have stars and you have to have at least two stars for it to be binary stars.
There may already be one. The nearest black hole known is a few thousand light years away, but it is easier to find black hole if they are part of a close binary system. A single star converting to a black hole, or a part of a binary system where the components are not very near, would be difficult to detect.There may already be one.

A star that is not part of a binary (or trinary) star system. The Sun is also a solitary star.

To be a solar system requires only one sun and things orbiting it. Most stars are by themselves, with things orbiting them. There are some binary systems, where two stars are together, but they are not as common and our solar sun is not part of a binary system.
Not exactly, while a pulsar is a specific type of neutron star (that being a "spinning neutron star") and a binary system is a pair of stars orbiting each other, a pulsar does not need to be part of a binary system. It would be possible, however to have a binary system with one of the pair being a pulsar and the other a neutron star (assumed to be the non-spinning or "normal neutron star" variety).
