MySQL Help

Searched to find this, but couldn’t find anything. Here’s my issue, I have 25 WP installs on separate domains (Bluehost). Unfortunately, I’m only now seeing the error of doing the auto-installer, as I have some sites that need to come down, but don’t know which database to remove.

While I realize this is probably a complete NOOB question, is there a way to figure out which database login is assigned to which site that I host?

TY in advance.
