You write "Nobody is restricted to having only one of the five main character traits. Many people are a combination of some, or all traits."
This is a complete misunderstanding of how big five works. Everybody have all traits, we have the traits to a greater or lesser degree. The traits corresponds to scales, and everybody has a score on all five scales. This means that for example on an extraversion scale one can have a high score, meaning one is very extraverted, or one can have a low score, meaning one is not very extraverted.
