It would depend entirely on the design or configuration. I would say minimum of 52 potentially more.

Would say 1 for each host and 1 for the router interface - 1 for the switch if it's managed / you intent to manage it.

Yes. Router's interface will need a IP address. All hosts will need an IP address.

You may also need another IP address for the switch, so you can SSH (Secure Shell) into it for administration purposes.
You may need more IP addresses, for "Router on a stick" - 2+ addresses for the router.

I'm gonna go with my gut and count the interface as an IP Address. If I was configuring this in Packet tracer or reallife, I would definately need an ip address on the router interface otherwise MY 50 host would not have internet.

I know the First and Last IP address are researved. IM not gonna count these...

figured out in my head.. Problem solved
