Can you have multiple SQL AGs on the same cluster?

From @hedgeb via Twitter:

"So building a #SQL AG in Azure #AzureResourceManager via DSC is not trivial :-(   Can you have multiple AG on same cluster?
Why in a  #SQL AG in Azure #AzureResourceManager do you have to have an internal load balancer?  Want to have multiple AG all on port 1433."

Thanks,
