In fact, the order of their withdrawal from the Seventh Wuhai should be several: 1 The sand crocodile was first knocked down by Luffy, exposing his attempt to occupy the kingdom of Alabama, being arrested by the navy and deprived of the title of the Seventh Wuhai.
Fisherman Jinbe was arrested for opposing the execution of fire boxing master. Later, he and Luffy escaped from prison and went to fight with each other. Also resigned from Qi Wuhai.
Black beard didn't want to be the Seven Wuhai originally, but he just wanted to realize his ambition in the name of the Seven Wuhai. Finally, it appeared in a big event, and after killing the white beard in the big event, it made a scene in the submarine prison and attacked the navy. Of course, he is no longer the Seven Wuhai.
In April, Guangmoria was not deprived of the title of Seven Wuhai after being knocked down by Luffy. Until the end of the big event, Wuxing thought that his strength could not keep up with the navy's strategy of marching into the New World, so he also instructed the flamingo Dover to get rid of him. Life and death are still unknown, but even if he is not dead, he will not be the Seven Wuhai again!
The rest seems to be still there. So far, the female emperor Han Guo has not been claimed as the title of the Seven Wuhai by the navy, so she still thinks it is the Seven Wuhai for the time being.
