Those are all most certainly different icon sets. The first image’s ‘globe’ does not match the second, and the second’s ‘house’ does not match the 3rd/4th’s ‘house’ icon, nor do the envelopes match for any of the images.
Seems like you’re fighting a losing battle to start with.
These are simple glyph style icons, just do a quick search and you can find many many sets out there. Good luck
