If any of these planets have developed life of some sort and assuming a carbon based chemistry and approximately the same environment as regards gravity etc, I wonder if they would be basically similar to us, ie. upright bipedal in form with binocular vision, an endoskeleton, a large brain close to the sensory organs and manipulatory organs of a similar number to us. If form follows function and natural selection is universal, then I would expect this to be the case. They need not necessarily be mammalian.
