That's going to be pretty constraining. I don't think you necessarily need 500 most of the time, but 70 is just to little for 6 people at once.
Most of the time, you'll probably be fine, but there will definitely be times where your network gets so congested that your video streams and gaming performance will suffer.
This is even worse if you're moving to something like a wireless connection, where packet loss is going to be worse, or a satellite connection, where latency will be higher.
