The victims were discharged from Loma Linda Medical.Center.
Ten victims remain hospitalized, including a 12-year-old girl in extremely critical condition.
The CHP said the bus driver, 61-year-old Won Chae, caused the crash when he crossed the yellow line on Highway 189, hitting an SUV and sending the bus plunging off the road.
Chae was the only person killed in the crash. He drove buses for a living and had volunteered to take his fellow church members of Light of Love Mission Church in Pasadena to a retreat last Friday.
Church members came together to pray for the crash victims on Tuesday night.
