There are broadly three categories of renaming you can use: Replace Text, Add Text, and Format. Rather than explicitly naming each file, you're instead giving macOS a set of rules to use to rename them all. The Rename Finder Items pop-up gives you a few ways to rename the files you've selected. The trick is in deciding which of the possible settings you want to configure.

Use the dialog box to rename your files.
