No, if you stop a sneeze halfway, the germs are not pushed back into your body. The sneeze reflex is triggered to help expel irritants or pathogens from your body, and blocking it may result in the viruses or bacteria being dispersed into the air instead.
A lot. Enough so that it becomes dangerous to try and stop it. One of the worst things you can do is to hold your nose and sneeze 'inward.' You generate so much force that the sneeze, I've heard somewhere, can propel mucous over 300 mph. If you try and block it, you can rupture blood vessels in your head, and even in your brain. So if you feel one coming on, let it rip and enjoy the natural and pleasurable sensation.
Your eyes shut automatically when you sneeze due to a reflex called the photic sneeze reflex. This reflex is triggered by the same nerve that controls your sneeze response, causing your eyes to close involuntarily. It is a protective mechanism to prevent bacteria or particles from entering your eyes during a sneeze.
