One of the three Hoenn Starters. Treecko, Torchic, or Mudkip.
By Ruby I'm assuming you mean the Hoenn starters, then yes, you can get one of three of them in HeartGold/SoulSilver
Trade with other people who have heart gold or soul silver.

toddile,chikorita and cyndaquil
The Johto starters, Tododile the Water Pokemon, Chikorita the Grass Pokemon, and Cyndaquil the Fire Pokemon
You can get three starters from different areas by completing the game (one at the beginning from johto, and after defeating red one from kanto and one from hoenn) but unless you trade or cheat there is no way to get all three starters from any one area.
yes but only by trade
You cannot get to Hoenn in Heartgold as it is a remake of the generation 2 game, Pokemon Gold and the only regions available in Heartgold are Johto and Kanto. You can however, obtain one of the three Hoenn starters by visiting a man from Hoenn at the Silph Co. building in Saffron City.
