Rotom, Giratina Dialga, Palkia, Cresellia, Arceus, Darkrai, Shaymin, Mesprit, Uxie, Azelf Giratina altered Form and Shaymin sky form.
Although Arceus, Darkrai, and Shaymin are not available anymore, they were just event Pokemon.
They are not found in the wild in Pokemon Platinum.
try to catch your legendary. It varies on which legendary depending on what starter you chose.

You cannot catch the legendary palkia on pokemon platinum but however you can use action replay to get it (most likely cheating)

Got the website in related links. It will tell you where to find the legendary pokemon, what levels they are and what they look like.
Empoleon is not a legendary Pokemon. It is the final evolution of Piplup, one of the starter Pokemon in Pokemon Diamond, Pearl, and Platinum.
it is not possible as legendary Pokemon are not breedable
you have to either catch a legendary or raise a Pokemon
