You should normally only need one ftp account for all the domains if they are on the same server.
It may be something as daft as you need to go up a diectory level with your ftp program to see the other directories for each of the secondary domains.

[edit reason] use example.com - not real urls [/edit]
So when I go to cpanel for site "aplum" I login as username "aplum" with password *******; and when I go to to cpanel for site "bingo3" I login as username "bingo3" with password ****** etc. through all 17 sites. This is also how ftp works for this serverplex....
Don't of course know how you're really set up, but perhaps this will help....
[As an aside, if your host is as clueless as you indicate, you REALLY need to move elsewhere!)
