You’re fine streaming at the same time as long as you’re all under the same public IP address. As long they detect only one public IP address at time it’ll be fine. If an account is being accessed from more than one IP simultaneously than you’re going to have problems. Also you don’t need to use VPN with Real-Debrid. But if you ever decide to do so again make sure nobody else is accessing your account.
