It is called an "alignment". A perfect alignment, all planets in one line, as is frequently shown in Cartoons for example, has a probability of zero. That is to say, it is so unlikely that it may be considered impossible.
"solar system" is the term used to describe planets orbiting a star. We know that planets also orbit binary and tertiary star systems, these would be different kinds of solar systems.

A group of planets moving around a star is called a solar system. Planets outside our solar system are called exoplanets. Despite the difficulty of detection, many hundreds have been discovered recently, orbiting other stars.

This is called retrograde rotation. Within our solar system, the planets of Venus and Uranus have retrograde rotation.
