You use "many" if the noun that word is modifying is plural and something that can be counted, such as marbles, cats, houses, computers, children, and on and on.

"Than" is a subordinating conjunction:
Scroll up a little bit to read an explanation between "than" and "then" (which usually shows up as a typo, but not always!).
