How to setup my office network to use 5 Public IP's

I have 4 servers each has Server 2012 r2 installed. Each also has NIC card that has 2 ports. And each also has a 3rd port to perform functions like turn the server on, etc. The 4 servers are Cisco C200 M2's to be specific.

I also have a 24 port unmanaged switch and a Trendnet TEW-633 router.

I have 5 static public IP's given to me by my ISP. But they did not give a router like TIme Warner did that has the ports for each IP.

I am not concerned about being behind the router firewall if that is not possible, but how can I set up these 4 servers to be on the same domain and each one be accessible using it's own public IP?

Do I need more/different equipment? Sorry for the noob question and thanks for any help!

Using what you have:
Cable Modem - connect to 24 port switch - connect EACH server to a port and assign a public IP. DONE.

This is HORRIBLY insecure and no one I know would recommend this.  But that's how you COULD do it.
(You would use the management ports or the second NICs.

Why 4 PHYSICAL servers?

You could virtualize them.

You could run Untangle (software based router) on one server or in a VM and assign all IPs to that and then forward whatever you need to the private IPs.
