Yes, it can, but not likely.
No, you could only obtain the red orb in Pokemon Soulsilver and Blue Orb in HeartGold
NO The Pokewalker was made especially and only for SoulSilver and HeartGold, so the only way you could walk a Pokemon from your Platinum game is if you traded that Pokemon to SoulSilver\HeartGold and then transfer it onto the Pokewalker
More legendaries like Pokemon Heartgold and Soulsilver.
I'm 95% sure that it is Groudon.
HS could refer to the Pokemon Trading Card set "HS - Unleashed", released in 2010, which features a number of updated Pokemon cards from Generation II. As the set was released not long after Pokemon HeartGold and Pokemon SoulSilver, not to mention the packaging uses the particular font of these games, "HS" could stand for HeartGold and SoulSilver.

you can probably find it on trees. or you could trade it over form diamond, platinum, heartgold, soulsilver, or RSE.
I don't think you can get Latios in Heartgold legitimately. I'm pretty sure you can only get Latios in Heartgold by using an action replay code, such as the Pokemon Modifier Code. You could also trade it over from Soulsilver, I think.
In Pokémon HeartGold and Pokémon SoulSilver, you can have 548 Pokémon in your game due to being able to put 540 Pokémon in your PC plus you could have 6 Pokémon in your party and 2 Pokémon in the Daycare.
in heart gold, you could get a kakuna in the national park when it's Tuesday, Thursday, and Saturday which is when the bug catching contest is.
You'll need to trade from the other Pokemon DS games, such as like: Pokemon Diamond, Pearl, Platinum, and HeartGold. You also could Mirage it, but you cannot get the Jade Orb by Miraging it.
