Charades is a classic, it is easy to google the rules. You can play reverse charades where the whole team acts for a single person guessing.
We play a game we call The Hat Game. Everyone gets five slips of paper and puts five names into the hat. Can be celebrities, book/film characters or people you know in real life, but they have to be names the people playing are likely to know.
You have two teams who have alternating 30 second periods to get their team mates to guess the names. In the first round you can say anything as long as you don't say the name. Then you out the same names back in the hat and play the second round where you can only say three words. Then put them back in and in the final round you can only mime. By the final round you sort of know the names in the hat, so it becomes a case of trying to work out if someone is miming Gandalf the wizard or the kids' class teacher. It always gets us laughing.
Another game (possibly not for the fainthearted) is Whose Pants Are These? Everyone donates a pair of clean pants and a volunteer model leaves the room, puts on a pair, and models them to the room. Everyone guesses.
It isn't exactly a parlour game, but rude word bananagrams can be quite funny in groups.
Again not a parlour game, but Secret Hitler is a good group game to play together.
