You can roll down as many windows as you want with relays, but the safest and easiest way is to use a window module. If you used relays alone to roll them down at the same time, one or more motors may continue to run until you have all of them down. Relays alone would be ok if each motor moved each window at the same speed, but most often they don't. On the other hand a window module contains additional components to sense current draw and/or static on each motor leg and switches each relay to each motor leg respectively to prevent overheating the motor. Besides other safety features they're designed to be activated by a momentary pulse which is the most common output of an RKE or remote alarm. 

To make a single window roll down or up with a relay, locate and cut the respective window motor lead. Connect the switch side of the lead to #87a, connect the motor side to #30, connect #87 and #86 to constant 12V+, then connect  #85 to a switchable negative source. The source could be an output of your RKE or alarm for as long as you hold the button or a rocker switch. To operate the other windows, simply wire an additional relay for each motor lead you want to operate.

Again, for the time and effort of using relays, a window module is the best way to go, especially with the additional safety features and benefits they offer.   

Hi Onthemoveauto, connect your remote turn on lead from your head unit to terminal #85, connect terminal #86 to ground,  connect  #87 to constant 12V+ (fused), then connect terminal  #30 to as many components you wish to turn on.
