Witnesses are persons who testify in court because they have some information about the case. A witness may volunteer to testify or may receive a subpoena (a legal document which orders him/her to come to court at a certain time to testify). Usually a witness is only permitted to be in the courtroom to hear the testimony of other witnesses once his or her own testimony has been completed. This is to ensure that one witness is not influenced (affected) by what another witness says in court.
