I'm pretty sure that's how it happens with one Bridge at least. Two Bridges may complicate it, but I don't think it does. I believe you can stack it so that they resolve in this order: Get a guy 1, Get a guy 2, RFG 1, RFG 2.
Yes, that's legal.
Note that, unlike with many other triggered abilities, the order is important here: if the RFG trigger is allowed to resolve first, the intervening-if clause in the token creation ability will see that the Bridge is no longer in your graveyard and you won't get the token.
