The easiest way would be to have a WIFI access point running off your Internet router (cable modem) and run Airport which is the Apple WIFI program.
I have a WIFI hub in one section of the house and a range extender at the farthest place where there was a decent signal. I can run my Mac, iPad, three laptops, a bunch of smart phones and an iPod that way...

You need to set up security on the WIFI connection WPA-2 is good for home use...

If your Macs do not have WIFI built in, you will need to run cables from each one to a hub which is then connected to your Internet router.
