Great pics!
Sorry I can't help with identifying the units, although someone here might be able to, but, from top to bottom the aircraft are:-
B24 Liberator
P38 Lightning
P61 Black Widow (night fighter).
P47N Thunderbolt
PBY Catalina
B24 Liberator
P47 Thunderbolt.
It's likely that, at the time, a number of units were either stationed on the base, or passing through.
