Networking Win32/64 computers at Mother's house?

[Harry Potter]

I'm looking to network some of the Windows computers at my mother's house and, when I'm there, my Win10/64 laptop. The computers to network include a Win98SE computer, a WinXP laptop, my mother's personal Win10/64 mini-tower and, if possible, a DOS laptop with no hard drive. All of the computers mentioned except the DOS laptop have USB ports, but the Win98SE computer's USB ports are all used. The DOS laptop is currently networked to the Win98SE computer to act as a hard drive via a null-modem serial cable. How much would this cost, and how do I do it? BTW, what benefits do I get by networking these computers?
