Milimani Chief Magistrate Francis Andayi made the ruling on Tuesday.
Charles Mberesero, Mohamed Ali Abdikar, Hassan Aden Hassan, Sahal Diriye will now have to defend themselves against the charges while Osman Abdi who was a security guard at the university during the attack was freed.
Osman had been arrested on claims that he colluded with the perpetrators of the April 2015 attack that claimed at least 147 lives, majority of them students.
According to Magistrate Andayi, the witness who claimed to have seen Osman taking photos was never brought to court and that there was no evidence showing he communicated with the terrorists. He also noted that the alleged photos were not produced in court.
The accused were jointly and individually charged with 156 counts including conspiracy to commit a terrorism act.
