Two stars revolving around one another (around their center of mass, to be precise) are called a "binary star". There is no special name for the case that the brightness is unequal; this is actually the usual case.
The term "stellar nursery" is sometimes used.

I think you need to better define what you mean by "configuration". If you mean a pattern of stars with which you can play connect-the-dots to form a picture in the sky, that configuration is called a constellation. If by configuration you mean a close grouping of stars, it would be called a cluster if the total number of stars was in the hundreds of thousands to millions, or even a galaxy of the total number of stars was in the hundres of millions to billions.

Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
If the curvature of the lanes of stars is sufficiently tight, one might call that a "spiral galaxy" in keeping with its visual appearance.
The real brightness of a star is called its absolute magnitude. This is a measure of the star's intrinsic luminosity, or how bright it would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.
