Will the rest of the Family Achike will be finally free after the death of Papa Eugene?

I think they had a terrible price to pay for this freedom. Jaja takes the blame for the murder and is put in prison. Even though Jaja willingly does this as his ultimate act of rebellion, Mama must also live with the guilt. I think that yes the family will be free of him in a direct sense . Indirectly, however, the scars will remain.
