Yes, the Hosted RPA license includes a Process licenses, so you do not need to buy it additionally, unless you want to have 2 concurrent flows and have one machine to host your flows on (the Process license does not come with a hosted machine).
To answer the additional questions:
- Yes, you can run as many different flows as you want with a Hosted RPA license, but only one at a time. This applies to unattended desktop flows and cloud flows that initiate unattended desktop flows. It does not include attended desktop flows or cloud flows that do not call desktop flows at all.
- Yes, if you want to run 2 flows concurrently (again, unattended), you would need two Process licenses (if you have your own machines) or two Hosted RPA licenses (if you do not have your own machines).
