Pic #1 is the big stupid, if yoy DIY than you only need YOU_ALL rating.
Pic #2 needs extension ring.
Pic #3 have to get code book for o/s pfl, but I have poked outside that way many times.
Pic #4 depends on the listing of the carflex, and I have always used the DB as support-if you are in the ground before you need support-the earth is support (has never failed on 16 yrs. of inspections).
Pic #5 all pole lights at some point will be held together by black tape and screwlocks sooner or later, shabby but safer than open splice (I always fix them even if it means custom made 4-s blank and tap and dye set.
Pic #6 white fittings are plumbing fittings.
Pic #7 may be high enough to not require gfi.
