Is there somewhere that says what the numbers mean? Specifically I want to know what the -1 is by AC Power, it used to be a 2.

The number behind the profile name refers to the index of the used profile, from the list displayed when using pmset -g profiles. If the number is -1, a customized profile is used instead (this means you modified your Energy Saver preferences from the default settings).

The asterisk denotes the profile currently being applied (battery or AC).

The remaining settings are explained in man pmset, section SETTINGS.
