How to fit three habitable worlds in our solar system?

Assume there are three earth-like worlds in our solar system. These three worlds would also have a single natural satellite roughly at the same mass-distance ratio of Earth to the Moon (about 1.2 percent of each of their masses and about 384,400 km distant give or take).

I'd put the innermost of the three is in the current orbit of Earth and the outermost is where Mars is. Where could the third planet and moon exist between the two that they'd be stable over significant time (billions of years)?

I am assuming all three would be habitable.

Can we fit those other two earth-like planets in our solar system? How?
