No, there are some Pokemon that can't be seen in this version, but if you use any GameShark or action replay you can modify the wild Pokemon to be anyone you want, So its possible if you use cheat programs.
There are 493 and I am not going to list them all here!
the easiest way is to hack.

Check Pokemon.com on the pokedex. All 493 Pokemon are catchable in Platinum.
493
Pokemon Diamond,Pokemon Pearl,pokemon platinum,pokemon heart gold and soulsilver.
Just raise all of them to level 100 and after that just doodle.
yes, otherwise you wouldn't have all of the Pokemon
There is only 493 different kinds of pokemon.
After seeing all of the Pokemon in the platinum pokedex (250 I think) and beating the elite four. you can get the national pokedex which contains all 493 Pokemon
