I also made such a mistake, introduced a lot of secondary heroes into the story, and then began to forget who and what and what is doing. I have already been told that an introduction to the story of more than two minor heroes is a mistake. I hope you as an author will be able to successfully remember all of these Jiro, Katoro, Say, Kay, Zeldman. I had to make an explanation. And this makes the text too boring. Well, probably you as an author know what you are doing. Good luck to you anyway.
