Regice can not be caught in HeartGold or SoulSilver. It can however be caught in Platinum, Ruby/Sapphire, and Emerald.
In every single Pokemon game and version, there are different Pokemon you can capture and train. In some games, you can catch one species of Pokemon, but not be able to catch it in another. In this case, surskit cannot be caught in emerald version, same with Roselia, while in sapphire and ruby, those Pokemon can be caught.
Faraway place is not a place you can get to in Pokemon Pearl. If you have a Pokemon that was caught in Faraway Place, it means it was caught in Pokemon Platinum in a location that doesn't exist in Diamond and Pearl (like the Distortion World), or caught in Heart Gold or Soul Silver. Any Pokemon caught in those games will say it is from Faraway Place.
