61 Cygni is a binary star system consisting of two orange dwarfs. Because of this configuration it is unlikely that any planets would have been able to form because of the gravitational tug of the two stars.
To date, no planets have been confirmed in this system.
Something is missing from your question. Cygni is not a star. The constellation name is Cygnus. The star will have a name like Alpha Cygni or 25 Cygni.
If the Moon is to a satellite, then Earth is to a planet. The Moon is a natural satellite orbiting Earth, just like artificial satellites orbit Earth. Similarly, planets are natural satellites orbiting stars, like Earth orbits the Sun.
The first moon to be discovered while orbiting Earth was the Moon itself. Other moons (like Earth's mini-moons or temporary natural satellites) have been detected over the years. These moons are usually small and don't stay in orbit for long periods, making them challenging to observe.
An object in space that circles around another object is called a satellite. Satellites can be natural, such as moons orbiting planets, or artificial, like man-made spacecraft orbiting Earth.
The string acts like the gravity of the earth. the circular motion of the ball imitates the orbit of he moon.

Yes.
16 Cygni Ab, it is named like this since it orbits the main star, with two stars orbiting outside it's orbit. there are four objects in that system. 16 Cygni A, 16 Cygni B, 16 Cygni C, and 16Cygni Ab. to find out how the names work, there are plenty of lists out there on binary star/planet system naming.

Perhaps orbiting around other stars, but we have yet to find them.
In terms of the earth, there is only one moon orbiting around it. In terms of other planets, some planets, like Mars or Venus and Murcury have no moons. Other's like all the Gas Giants have more than one moon orbiting it.
it is dust and rocks/debris orbiting the planet, it is like how the moon orbits earth.
No, circular motion can occur in both natural and artificial systems, not just on Earth. Objects like planets orbiting around the sun and satellites orbiting the Earth are examples of circular motion occurring in space.
in order for it not to become spherical, it would have had to be much smaller. if it was much smaller, it would just be some rock floating around like the millions of similar rocks orbiting the Sun.
There is no single planet called "Super Earth." Rather it is is a new class of planet; similar to Earth in structure and composition, but larger. A number of super Earth planets have been discovered orbiting other stars. Note that such planets to not necessarily have surface conditions like those on Earth, but simply have rocky surfaces.
Our scientists have located about 400 "exoplanets", planets that are orbiting other stars. We have not yet found any earth-like planets; so far, every planet we have discovered is very massive, more like Jupiter than Earth. But our instruments are barely able to detect even giant planets orbiting nearby stars; there is no possible way that we could identify a planet 20 million light years away, which would be in a different galaxy. So the answer would be, "We don't know. Yet."
An object that moves around a larger object in space is typically called a satellite. Satellites can be natural, like moons orbiting planets, or artificial, like spacecraft orbiting Earth. They move in a regular, predictable path due to the gravitational pull of the larger object they are orbiting.
