Welcome to Just Answer!!

The first code is for a right rear abs speed sensor , the second fault is for a front right speed sensor , third one is fro the left rear , the 4th one i have a question for you was this a engine control module fault or abs control module fault . Make sure the abs sensors are showing the correct readings with your scan tool while moving if they are more then likely you have a faulty abs control module which is attached to the abs pump these are very common to fail. I hope this helps .

Positive feedback is greatly appreciated thank you
