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.
