Also, a strianght thru LAN cable is jus a simple LAN cable (also known as RJ45 cable) wich will connect all ur 4 PC's to the LAN Switch and the LAN Switch will connect to ur router (using wich the internet can be surfed) and this router can be connected to ur main PC
Get a 4 port+wifi LAN Switch (where the 4 port are LAN ports (using RJ45 cable) and a single wifi port can be used to connect ur one Lappy via wifi
Get a LinkSys or netgear 4port+wifi LAN Switch wich will cost u around Rs.1700-1900/- and the LAN Cable (RJ45 cable) will cost u Rs.7 per meter also, all the 4 Systems (2PC's adn 2LAppy) shud hv Ethernet (LAN) card or ethernet (LAN) Port..
AN Ethernet (LAN)card shud cost u Rs.200/-
