Russian stacking dolls (I forget what they're called, but they're doll within a doll within a doll x however many times) with planets anybody? :D

Looks like we've got the whole RANGE of sizes between mercury and mars and between mars and earth and beyond. It shouldn't be s surprise that such a range exists, but this is just cool!

Edit: The exoplanet app shows one that is just inside that stars habitable zone, however there could be room for more a little further out and still be in the hab zone. The one that is in the hab zone is a bit bigger than Mars but might be too hot. From the diagram in the app, looks like there could be room for up to two or three planets and still be in the habitable zone.

Russian dolls, that's what they are called.

In fact, they are actually called Matryoshka dolls in English, however, Russian nesting doll is the informal English name.

Yea, Russian nesting dolls is what I was getting at.

Okay, now, since Mars is about 0.10 earths, and Mercury is about 0.06 earths, taking into account the average density of the four rocky planets in our solar system, could we be able to assign approximate masses to them this way?

Assuming that most red dwarfs have a slightly higher metallicity, I think it would be safe to assume that the average density of that system would be about 5.5g/cm^3 to 7g/cm^3, since metals have a higher density.
