I'm sorry, but articuno isn't in pokemon pearl, it's only in pokemon platinum (talking about the ds games)
No trainers will have articuno.
In Pokemon Diamond, I found Articuno in Safari Zone, I just don't know if it works in Pokemon pearl, (Area 1)...
You can't catch articuno in pearl unless you migrate it from firered or leafgreen.

No, in Diamond and Pearl you can't catch the legendary birds.
In Diamond and Pearl you can't catch Articuno.
You have to migrate them or use the Action Replay.
You must migrate from FireRed/LeafGreen or trade from Platinum.
No-one of the pokémon you mentioned can be found in Pokémon Diamond or Pearl.
you need to catch it first in fire red/ leaf green and migrate it to pearl after you beat the Pokemon league.
You can't get Articuno in Pokemon Ranger.
