They are being held in police custody in connection with the stabbing of 14-year-old Paul on April 6th outside his Leytonstone home in east London.
The latest arrests come after four other teenage boys appeared in court charged with the murder.
A 15-year-old boy and a 17-year-old boy appeared at Waltham Forest youth court last Friday, while two other boys, aged 13 and 14, appeared at the same court earlier that week.
All four have also been charged with the attempted murder and grievous bodily harm (GBH) of another boy, a friend of Paul's, aged 15.
They have been remanded in custody to reappear at the Old Bailey later this month.
Three other male teenagers, aged 14, 15 and 19, have been released on police bail to return in June pending further enquiries.
