Not alive that I know of. But there is speculation that microorganisms may have helped bring life to this planet. Some rocks found on mars had microorganisms in them albeit dead. Some scientists believe that a microorganism may remain dormant within a meteor. When the meteor crashes on a planet it disperses the microorganisms. If the conditions are perfect on the planet the microorganisms may revive. That's all speculation though I find it hard to believe.

Yes, for sure, first, we have found bateria on Mars, and second we have left human microorganisms on space everytime a shuttle leaves the planet.

There could be on other planets, but none have been discovered so far.
Sounds like your asking if there are any in the actual space between the heavenly bodies. If so then; no. As the space between the planets is cold and without air or water.

Sure, we've got two astronauts in space with their cmoplement of human flora and fauna, plus all the equipment used by moon and other missions having been touched by humans, leaving rhinoviruses and the like.
