I do not know if this is the right place for this but if I was to assembled a team from different state could we use the some account for game Dev.

AFAIK - each user has to have their own Epic Account in order to access Unreal Engine. This isn’t a problem because the account is FREE. You can also share assets as long as it is only used in the project you are all working on and that at least one team member legally owns it … there are some considerations to keep in mind.
