Can you observe people’s aura when they’re with their partner/social group

Sounds intuitive but not sure if it’s from my sensory observation or not. But can you kinda sense if someone belongs to their partner or their group of friend? Like their/your aura increases or drops when with someone

(Examples below if you want to read)

For example:

I can see if my friend is compatible with someone or not by seeing her and that guy’s reaction when they’re together. I think it came from small reactions, like their reactions when they’re doing sth new together or the way they react during social group. I can tell very easily from just a short period of time when I get to observe them. If they’re good together, you can see that they look a lot prettier with each other than with someone else.

Another example from my own experience:

I can see that my aura kinda dropped when I’m among high Fe users. Maybe it’s because I was quiet, reserved, and awkward when I’m around them comparing to their social interactions. The other reason might be because I didn’t get to express my Ti in a full mode without fearing it will offend them. Not to mention that having to force myself to show some reactions to accommodate others is 7x more awkward than staying quiet. I’m not saying they’re incompatible with us or anything. Actually, they’re very kind and caring and I always feel adopted, especially during the time when you have to do sth you’ve never done before. Their forgivingness and patience are really admirable. On the other hand, when I’m with thinkers, it’s a lot different. I see my aura increases when I challenge their thinking without fearing they will be offended. I think my aura increases when I can be direct, emotionless, and skeptical openly, which often times when I was with xxtp and some Extj.
