3 pair for banana plugs will enable you to connect 3 speakers or 3 sets of speaker terminals on the receiver. Each channel needs one pair, one plug each for + and -. Since you have the HD500 they only need bare speaker wire but you can use banana plugs on the back of the Pioneer receiver which is very convenient. You've got a 5.1 speaker system, you need 5 pair of banana plugs and one subwoofer cable. Order two more sets of banana plugs.
