1. It does that and provides the capability to have an USB drive plugged in and shared.
2. It has three ports for hooking up devices with an Ethernet cable for wired network and Internet access.
3. Only if connected through Ethernet or the other router is an AirPort base station or Time Capsule.

1. The most recent AirPort Extreme supports 802.11a/b/g/n/ac. There's nothing special.
2. Are you referring to the DSL port? In that case, you have a modem-router. If you want an AirPort Extreme, you need a modem where the DSL cable is connected to, and then you have to connect the AirPort Extreme to the router using an Ethernet cable connected to the WAN port of the AirPort.
You can connect your computers wired to the AirPort Extreme. It has got four Ethernet ports.
4. Of course. If you want to set up the AirPort Extreme with Windows, just download AirPort Utility and follow the steps > http://support.apple.com/kb/dl1547
After setting up the AirPort Extreme, you don't need any software to connect to it
