not a native korean speaker or a fluent one at that, but i think most groups use banmal to speak with each other.
yes, you're right that the younger speak formally to anyone older than them and the older speak informally to anyone younger than them but younger people can be granted permission to speak informally by those older than them. it's a sign of their closeness. they would still use words like hyung and unnie as a sign of their respect but not necessarily formal language.
here's a good explanation of banmal and how and when it's used - http://www.dramabeans.com/2010/07/glossary-banmal/
in terms of on camera and off, i think everyone is more mindful on camera. so, "shi" might get attached to names instead of "hyung" or "noona" but it's more when you speak of a group member rather than speaking to them. there off camera, there's probably more swearing and slang :D
