3 are black and 2 are green. Are these all interchangeable ?

The black ones are all the same, so interchangeable. 3, 4 and 5 in diagram.
#5 position, AC clutch relay, should use updated relay part # 39794-SDA-A05
Updated relay made by Mitsuba, not Omron. I updated all 3 black ones fwiw, but most say Omrons are ok in the two fan locations, just not ac clutch location 5.

Not sure if green and black ones are interchangeable.
ETA; No, they are not interchangeable, between colors. See next post.
I now believe that is your question after reread.

Black ones still come from 2 manufactures, Omron and Mitsuba.

No green info.

Discovered some green relay info;

The green and black relays have protruding tabs on the sides that fit into slots in fuse housing. The black relay has tabs in the middle, the green relay tabs are offset so they are not interchangeable. Between colors that is. They will not fit in other color positions due to the tabs. The green one is also taller than the black ones w/likely different ratings than the black ones.

Green Omran made in Japan; 39792-SDA-A01 ( ? ? )
Newest black Mitsuba made in Vietnam; 39794-SDA-A05 (ac clutch)
Original black Omran made in ? ? ? ; 39794-SDA-A03 (radiator fans)
