I want to know which one of these drugs should he be detoxed first.

There is really no exact of how patients are detox , depends on the facility . With all the different things he is addicted to , it will probably take some serious medical supervision and planning to go through a safe detox. The best way is calling each treatment center and discuss their plans based on the patients history and then choose the one your think is the safest.
Best of luck.
