interior Length and height and width ??

The interior is 8" wide by 5 1/2" high.

I am looking for a lockbox for the Honeywell Thermostat RTH6580WF1001/W. The dimensions listed dont make sense. Which will fit this Thermostat?

I don't think it will fit. It's approximately 3.5 inches protruding from the wall and 9 inches length and 7 inches height.

my thermostat is almost 7 inches wide and almost 5 inches in debt will it fit

Do you mean 5" deep or 5" tall? If your thermostat is 5" deep then I don't believe that this will work for you.

I'm going to put this over a 2 light switch location. Will this fit?

it depends on the size of the switches.
