Are trinary star systems possible?

Yes, there are triple star systems, and also quadruple, quintuple, etc. However, they tend to arrange in subgroups. Say you have a triple system with components A, B and C. Probably you'll have A and B orbiting together closely one to the other and the C component orbiting both A and B from far away, as if A and B were a single star. The reason for this is that a configuration where A, B and C all orbit one another is very unstable and sooner than later one of the components would get flung away.

EDIT: Typo.
