Yes. Mars has a relatively stable temperature that living things could survive in with some modifications. Mercury has no atmosphere and so the days are blisteringly hot and the nights damagingly cold. Venus is a pressure cooker that melts lead both during day and night.
There are 13 in total: Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Dwarf planets: Ceres, Pluto, Eris, Makemake, and Haumea. It seems likely that several other large objects, such as Sedna, Qaoar and others, will eventually be recognized as dwarf planets. It also seems likely that more dwarf planets will be discovered.
What is the reason that life is less likely on the outermost planets compared to the innermost planets
No, there are no natural or artificial satellites known to orbit Mercury. Mercury is the smallest planet in our solar system, and its proximity to the Sun makes it less likely to have captured a moon compared to other planets.
Yes, Mercury has both valleys and mountains. Some of its valleys were likely formed by tectonic activity, while its mountains are thought to be the result of volcanic activity. Mercury's surface features are the result of a combination of tectonic forces and volcanic processes.
Since Earth's Moon was likely formed from a chance collision, the formation of moons may not have been a stable process in the inner solar system. Any moons that formed around Venus or Mercury could have been swept away by the stronger gravity of the Sun, as might smaller moons around Earth. If Mercury or Venus ever had satellites, they were lost long ago.
Not likely.

No. The planet we are most likely to colonize is Mars.

Probably.
Considering water is made with Oxygen and Hydrogen, the only planets that could have water on them would have to have plants. Humans haven't discovered many planets due to the difficulty. We are not advanced enough to know much of this. As space exploration goes on, people learn knew things about the Universe and planets. If humans ever did find a planet with wildlife on it, we'd probably land there, and manage to survive. Humans would most likely eventually colonize on other planets. However, the chances of planets in our solar system having wildlife on them is slim, and to find these, we'd need to travel very far from Earth, once again bringing my point that humans are not advanced enough.
Methyl mercury is more toxic to humans than inorganic mercury. Methyl mercury is a highly toxic organic form that can accumulate in living organisms and bioaccumulate in the food chain, leading to potential health risks when consumed by humans. Inorganic mercury compounds are generally less toxic and less likely to bioaccumulate.

Mercury. Comment: You need ESP to answer questions like this. However, I think Venus is the most likely answer.
