1. Better you ask this kind of question in technical forums.
2. well to the computers that u will use in the offices apply non static ip's for example 192.168.32.* or 10.*.*.* if the servers that u will use they will have to be accesible from computers outside the bussiness u have to install to them static ip's that the ISP will provide to u. but if the server are only for local use and not internet access then u can use non static ip's. i see above that u want to put on some services , email for example must have also a domain name,except from the ip. To be honest mate if u dont know the ip(protocol) ask from someone to help u with the whole implementation, the things that i have write above are general and to implement all this thing that u want is not just ip.......u have to be able to setup the routers/switchs,services,operating systems for the services,etc
3. You can use non-routable ip's internally (192.168.X.X or 10.X.X.X). If you are trying to provide services to the open internet you need routable ip's. The firewall and routing configuration for this is difficult to generalize, but I would recommend using a DMZ style setup and working from there. Easy part - 192.168.1.0 - 192.168.1.31 /28 192.168.1.32 - 192.168.1.63 /28 192.168.1.64 - 192.168.1.95 /28 192.168.1.96 - 192.168.1.127 /28 192.168.1.128 - 192.168.1.159 /28 5 subnets with 30 available addresses ( /28 = 255.255.255.224 for the subnet mask) If you exceed 30 devices you will have to redo this subnetting, have fun. :-)
