Cosmic rays bombard the upper atmosphere (see Carbon 14 wiki):
"Carbon-14 is produced in the upper layers of the troposphere and the stratosphere by thermal neutrons absorbed by nitrogen atoms. When cosmic rays enter the atmosphere, they undergo various transformations, including the production of neutrons. The resulting neutrons (1n) participate in the following reaction: : 1n + 14N → 14C + 1H"
Yes, water vapors enter in the atmosphere.

Carbon can enter the atmosphere. It moves in and out of the atmosphere through the earth's regular carbon cycle.What it can not do is enter as pure carbon. Carbon is a solid in it's natural state and solids fall out of our atmosphere. Carbon must mix with a gas, such as oxygen, to create another gas, carbon dioxide, to enter the atmosphere.

It doesn't "enter" the atmosphere, it comes from the large mass of the earth which creates a gravitational pull.
Usually they will burn up due to the friction they encounter when they enter the atmosphere, or they will bounce off the atmosphere and be deflected into deep space.
