You can catch Dialga, Uxie, Azelf, and Mesprit
No. It is a friend area in Pokemon Mystery Dungeon Blue/Red Rescue Team.
Mystery gift sends you items that unlocks legendary Pokemon, or it sends you the legendary Pokemon itself.
The Pokemon you can get before the national dex is Dialga, Mesprit, Azelf, and Uxie. After the national dex is Giratina, Cresselia, Regigas, and Heatran. With mystery gift is Shaymin, Arceus, and Darkrai. You can get other legendary Pokemon by migrating/trading.
Depends where you count it! I suspect you are referring to Mystery Dungeon? There, you could count it as a boss, but no, not a legendary. That means there is only one/ extremely rare. No, no, no, not at all for Diamond/Pearl.
recruit legendary Pokemon
It is a Shaymin (a grass/flying type legendary) obtained only through mystery gift events unless you use cheats.
