Commerce 2.0: How can multiple email addresses receive copies of orders?

See our documentation for order receipt emails: https://docs.drupalcommerce.org/commerce2/user-guide/orders/customer-emails

I think you'll be fine adding those four emails separated by commas.

EDIT: Also see our docs for setting up HTML emails https://docs.drupalcommerce.org/commerce2/developer-guide/core/html-emails
