IMO, the agreement is not true.

Ravel will be like the other girls of Ise in his harem.

The Pheonix family just gave their blessing to Ise and Ravel just like how the Gremory family gave theirs to Ise and Rias. (though Ise doesn't know anything.. Ise sure is dumb).

And for the "arrangement",

I only am sure for the top 3,

Rias will be the legal wife,

Asia the second,

and Akeno the third. (this is stated by Akeno so I think that will be true.)
