No they still serve their master since they only became a Devil through their master's Evil Pieces, that can't change. The only thing that changes is their status in the Devil's society, like Tannin gained his own territory when he became an Ultimate-class Devil. Also the reincarnated Devils are free in a sense, cause after they gained their own peerage they need to sustained his team himself without his/her master's help. They just need to continue to serve their master when in need only, other moments they don't really need to follow their masters so much anymore.
