OK. I don't think any of those would be habitable. Orbiting that close to even a red dwarf would probably mean the rotation is tidally locked with one side always facing the star. Also, red dwarfs are known to be flare stars, so after a few million years, the atmospheres would be stripped from the planets by the intense UV and solar winds especially on the inner 6. I refuse to get excited about small rocky worlds orbiting red dwarf stars.
I disagree. Potentially habitable stars around red dwarves are PRECISELY the kind of planets we need to be looking for.
Our sun is a mid-sequence star. Its lifespan is about ten billion years, and it's about halfway through that right now. Within a couple billion years, possibly even less less, it will have increased in heat so much that Earth will no longer be habitable.
A red dwarf, on the other hand, has a lifespan two to three orders of magnitude longer, measured in the trillions of years. If our goal is sustaining life after Earth's destruction, those are the planets that provide the best chance of a stable home to terraform and colonize. The fact that these planets, as well as even closer Proxima Centauri b discovered last year, are within a distance that life could be sustained and transported to them before the specimens die (at least in theory) is cause for a major sigh of relief.
If we're looking for existing life, perhaps not so much, but that is a much bigger crap shoot.
