I was just wondering how to get another emote, or if there are any others apart from "Hammer Time" etc.

The new emotes were a part of the Collectors Edition of Destiny which gave owners of it 3 exclusive emotes, class items, and shaders (1 of each for all 3 character types). Players who own TTK plus the first two DLC's can buy the collectors items for a stand alone price of 20$ in U.S pricing.
