So it could barely takeoff from a standard commercial runway? (I'm sorry for all the questions)

Depends on the runway.

C-5 will not be the workhorse, too many problems with them. The other cargo planes will do the work.

spectr17 is right about the C-5 needing a reinforced runway. I don't know the specifics, or if a standard runway is considered "reinforced" enough.
