Why are these fuses here?

2011 Sport 5.7. One of my DC12V plugs was dead so I figured out which fuse it was and will replace with new 20amp in slot 6. However I noticed 20a fuses in both slot 9 (rear heated seats) and 14 (back up camera). But I don’t have either of those on the truck. Are these just extra 20a fuses that I can use elsewhere? And why does slot 7 have 3 receptacles for a two prong fuse? Thanks!!

3 slot is so that you can set it to always on or ign controlled.

Cool! I heard about that functionality, but on a different year. Thanks for clarifying
