The first legendary you get in platinum is Giratina!!..
latios,latias and i think tauros cause i got a legendary Pokemon tin and it showed tauros deoxys raikou on there. some semi legendary Pokemon are rotom (from platinum and Pokemon p/d) lucario (from Pokemon platinum and p/d) (latios and latias are fully legendary Pokemon) hope i helped im 90% im right.
you cant without trading. and which dog you encounter depends on which starter you choose. but you only get to catch one out of the three in the game by yourslef
i think there is about 12 plus regigigass and manaphy and phione and also if you concider rotom to be a legendary and if you have an AR YOU CAN GET ARCEUS DARKRIA AND SHAMIEN AT THE SPECIAL EVENT.
Go in to every Pokemon gym and get beaten at least 10 times againgst the gym leaders.

You must win all the tamer test in the digicolleseum, first brons, than silver, gold, platinum en last legendary.
They are not found in the wild in Pokemon Platinum.
first you have to battle with every pokemon like i did! it took me a long time but i did it on platinum i also have all legendary pokemon

None.
try to catch your legendary. It varies on which legendary depending on what starter you chose.
shaymin then after shaymin the first legendary Pokemon ARCEUS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!and also chicken butt
You cannot catch the legendary palkia on pokemon platinum but however you can use action replay to get it (most likely cheating)
Yes you can catch the three Legendary birds in Platinum but you'll have to beat the game first and to minor side activites before hand
no
articuno,zapdos,and moltres
it is not possible as legendary Pokemon are not breedable
