All five were remanded in custody for sentencing on May 22.
The five had been on trial since March 3 and the jury retired to retire their verdicts on Wednesday.
Mr Jones, 40, died in hospital from serious head injuries after an attack at his home in January last year.
The supermarket worker was fatally bashed in a "vigilante attack'' in retaliation for an alleged rape, the court was earlier told.
He suffered massive head injuries and died five hours later in Wellington Hospital.
The Crown said Mr Jones was attacked by the four charged with murder while Miller waited on the street.
The court was told Mr Jones had some disabilities, including learning difficulties and epilepsy. He lived independently at his small flat and had worked at a supermarket for 15 years.
