They have their own orbits, around the star they formed around, just like how our planet orbits our sun.
Ptolemy thought the earth was the center of the universe, so that the stars, the other planets and the sun revolved around the earth; Copernicus realized that for the orbits of the planets to make sense, the earth and the other planets had to revolve around the sun.
Yes. A moon (or natural satellite) do revolve around other planets besides Earth. The only two planets without moons revolving around them are Mercury and Venus.
The sun cannot revolve around the planets because it is at the centre of the solar system. Thus, it is like the central body around which all other bodies revolve.
The revole around the sun
Polaris is a star, and it doesn't revolve around any planets. It is possible that other planets revolve around Polaris, but so far I'm not aware that anyone has looked.

Circular orbits are unstable; any outside influence (i.e. other planets) will distort them. Elliptical orbits are self adjusting.

the sun's gravity
according to newton's law of gravitation every object in the nature attract other due to its gravitational pull so planets revolve around sun.
The sun heats up the planets and forces them to revolve around it.
round but some rounder than others. Every object is in an orbit which is an ellipse. The planets are in orbits which look almost exactly like circles with an offset centre, but some comets and dwarf planets have orbits with a high eccentricity.
