I have about 2 or three voices going in my head, would that be a sign of schizophrenia?

The presence of auditory hallucinations is a symptom that can be present in other illnesses as well, such as major depression or even some personality disorders. Your description of voices in your head is unclear and not enough information to provide a diagnosis. You should seek professional help to assis you in a diagnosis.

Possible: Possible, but other symptoms need to be present. Evaluation by a psychiatrist is required.

Yes: Although, other conditions besides schizophrenia are possible. A classic sign of scz, has to do with when a person hears several voices in his or her head at once and the voices are having a conversation among themselves talking about the individual in the third person. Btw- there are excellent treatments available for this brain disease which affects 1% of the population.
