You can just let it grow and it will come in fuller. Your hair is genetically predisposed to grow in a certain thickness and in certain areas. There is little you can do to make it thicker than it already is.
Shaving does not "make your hair grow back thicker".
Nothing that you can put on from the outside will make your hair grow thicker. (With the possible exception of Minoxidil.)
yes
To make your hair grow longer you could try oiling it and giving it a trim- to make it get thicker then you'd have to try not washing it for a while and let natural grease into your hair to make it healthy [i think =) ]

No. Cutting hair will not help it grow, nor will shaving make hair grow in thicker. Hair grows at varying rates depending on changes in internal body chemistry.
No, it is not true. Cologne has no effect on hair growth. Hormones do.
It is good for the hair but may not make it thicker it may be healthy.
Yes, if you shave your hair it will grow back faster, and thicker. (The same will happen if you cut/trim it, or wax it).
