Group chat and token use

How does Group chat work with Context Token?

For example. I have it set for 8192.

I have 4 people in the chat.

Each person Description takes up say 500 tokens

The First message takes up 100 tokens

Personality Summary takees up 50

Example Dialog takes up 100.

Scenario takes up 50
So that would mean 800

So with 4 people in the chat , does this mean that I am already using 800*4 tokens(3200 Tokens)

I got more questions but wanted to start with a general understanding of how it works
