My current termostat wires from wall are white,yellow,green;orange,red,blue .
My new thermostat has connectors the say G, RC,RH,Y/O,W/B,Y1

What do I do?

The thing to do is return the new thermostat to the place of purchase, and select one that is compatible for your system (2-heat/1-cool/heat pump). While you're at it, do yourself a favor and choose something other than Hunter. The few extra bucks spent for a Honeywell will be well worth it.
