As far as I'm aware, that's the only ones that have been released outside the game by SE (those other two you posted are the same one repeated). During the game however Alphinaud mentions Louisoix's journal repeatedly, so it's likely he's referring to it for guidance and information (like
when he asks Cid about Gaius and Alphinaud realizes he's the 'Black Wolf' Louisoix mentioned 'in his journal').
But at the moment, those two are the only quotes from it (I think Urianger might have quoted other lines from it at times, but I'm not sure.).
