Every badge here comes from the names and descriptions in the hotel's game texts. Most came with the Habbo files the hotel is built on, so being listed doesn't mean it can be earned or given out at Peace.
Categories are a best guess from each badge's code and name, not official. Peace marks badges the hotel seems to have added itself: written in Malay, mentioning Peace Hotel or Malaysia, or typed in by hand.
