Compatability with Nest Thermostat

Please assist in compatibility with any of the Nest Thermostats...

Based on the fact I can see E, AUX, Y, G, O, R, and C wires, your system should be compatible with the Nest Learning Thermostat (not the other models). Of note, it looks as though you have a dual fuel system.

The Compatability Checker asked if it was a dual fuel system...How do I confirm that?

There's a section on dual fuel systems in the article I linked above but essentially, you have a dual fuel system if you have a furnace and a heat pump. If you’re still not sure, contact a local HVAC professional. As it mentions, it’s important for a professional to assess the requirements for your specific dual fuel configuration, if you have one, since choosing incorrect options for a dual fuel system can result in damage to your system.
