For me the hierchy goes like this:

Pirates (including Yonko and Warlords)

WG (Including Marines)

Revolutionaries

I know you would react to why i include warlords in pirates well after all they are still pirates right? if we were talking about Hierchy for each groups that is known then i believe it goes like this

WG

Revolutionaries

Yonko (All four)

Pirates(their ranking would be higher "if" they worked together.

Warlords

I don't think its impossible for all (most) of the pirates to work together. i mean look at Whitebeard he manage to gather 40+ strong pirates together. The only way i can see all the pirates working together is when the New Pirate King Appear.
