How to use theme_hook_suggestions()
Replace the underscore with a hyphen, and you get the name for the template file.

If the suggestions you are getting are the ones reported by theme_get_suggestions(), then they are the ones returned from template_preprocess_html() for a page at /profile_personal/113/edit.

The first suggestion would be applied for all the pages with a path starting with /profile_personal/; the last suggestion would be applied also for a page with path /profile_personal/edit, and the one before the last would be applied also for /profile_personal/113/revisions. 

Whichever you choose, you should always check the path of the currently show page, via arg().
