Are your TTNGs in one big reality zone, or do you have a TTNG for every couple? I have different TTNGs for separate couples, but these are considered by 'real' TTNGs:

Skyfire and Silverstar ~ Robin/Starfire
Rob Logan ~ Beast Boy/Terra
Elliot Sturt ~ Raven/Goth Dude
Michelle Stone ~ Cyborg/Bee

These are all the TTNGs I have created that all know each other and are all friends X3. However, they all have their friends that know them better than the others, like:

Rob and Silverstar. Both are shy people. Mix that in with typical teenage confusion, and you know they'll need someone to understand them, someone who aren't their parents. Skyfire and Elliot hang out together, because Elliot is slightly gothic and Skye likes to poke fun at him. The basis of their friendship is based on teasing each other. But inside, they know they care deeply about each other. Michelle has never had any friends that she totally connected with, so she's just beginning to fit in. She hangs out more with Skye and Star.

What's your TTNG 'family' like?
