Duplicate photo filenames

To save space I have been moving some (work related) photos to the SD card. The problem with this is that any new photos I take start reusing the same filenames e.g. DSC_4567 meaning I've got duplicate filenames across my device.

Is there a way to rename them?

Is there a way to make a list of filenames so I know what's going on?

I intend to make more use of Google photos app (or another if recommended) & backup all my photos but before I do I want to understand what will happen to these photos with duplicate filenames.

MY phone is Sony Xperia Z5 compact
