Two were for text use: "Ever Crisis" and "The First Soldier." It seems reasonable to believe that these two are both related to the Compilation of Final Fantasy VII, given the use of the terms "Crisis" and "Soldier" in other ways related to FF7. The third is more explicit - it's a trademark application for the logo used by Shinra Electric Power Company. The two text trademarks were filed on December 17, and the visual on December 22.
There's no other information about how these marks might be used, as only the Shinra logo has been used in the past in its current form. The other marks could refer to remakes, remasters, or new games in the FF7 universe for any platform. They could even refer to upcoming books based in the same. They could even be for projects that never actually happen. We will just have to see what happens with them in the future.
