How do I get a child who is not immediate family in my custody again?

You would need to file a motion for custody in the juvenile court. Cases like yours are very difficult as you need to prove both parents unfit and that you would be a proper custodian of the child.

In Ohio, the short answer is: you ask the court to assign the child to your custody in the best interest of the child. But a question that brief has a story behind it. You need to tell a lawyer the whole story. Please seek out an attorney with domestic relations and juvenile court experience to help you. This is NOT a "do-it-yourself" project. The above article does not create a lawyer / client relationship, nor should it be taken as legal advice.
