Suspect the top one is a USAF F-4C/D, you can see that the leading edge of the starboard inboard wing pylon curves down. That was a distinguishing feature of USAF F-4s. On USN/USMC/RN/RAF F-4s, the inboard wing pylons had a straight leading edge, as on the RAF FG1 in the lower picture.
BTW, for completeness the bottom one is a Phantom FG1 of 43 Sqn, RAF Leuchars*, circa 1969-1972, but you probably know that! By 1973 most RAF Phantoms were wearing the red/blue “tactical” roundel (which should have been the Type E, but was never formally designated) in place of the red/white/blue Type D roundels in the pic.
43 didn’t use FGR2s, it was formed on FG1s originally ordered for the Fleet Air Arm (likely for 899 Sqn on HMS EAGLE), but rendered surplus to RN requirements when the 1960s Wilson government decided that the Navy didn’t need aircraft carriers any more.
*20 miles from my home town. In my high school years we saw and/or heard 43 Sqn ‘Tooms (and 5 & 23 Sqn Frightnings) overhead almost daily 🙂🙂
