Gary Convie, 24, and 44-year-old Eamon Fox were sitting in their car at a building site in North Queen Street on 17 May 1994 when a gunman opened fire with a submachine gun.
Officers from the PSNI's Serious Crime Branch detained a man aged 48 in north Belfast and woman aged 41 in Antrim on Wednesday. They are being questioned in Antrim.
Three men aged 43, 52 and 65, who were arrested in Templepatrick, Newtownabbey and Antrim on Tuesday, have been released pending a report to the Public Prosecution Service.
One man has been previously convicted of the killings and in January a second man was charged with the murders and is currently on bail awaiting trial.
A spokesperson for the PSNI said: "The arrests are part of Operation Stafford, an investigation into a series of murders and other serious crimes by the UVF in north Belfast."
