So I have a 100 AMP panel that has a 90AMP energizing it. I have 1 Tesla Wall Charger with a 50 AMP breaker and set to #8 inside Tesla charger. I was going to add a NEMA 14-50 with a 50 AMP breaker in the same panel. So what will be wired to the panel are Tesla Wall Charger with a 50 AMP + NEMA 14-50 with a 50 AMP + GFCI with 20 AMP

Adding NEMA for non-tesla EVs...will panel/feed be enough to handle this?

So, with 90 amp you don't want anything down the chain to use more than 90*0.80 = 72 amps. I think it's ok if you are not using all the elements on the circuit simultaneously.

Might want to call the town inspector for advice.
