I have updated to Mountain Lion Server. My terminal commands are 'rusty'.

I want to change the permissions on the network home directories to match the firststudent in the list for the secondstudent:

macserver1:school data sahtudec$ ls -l /'school data/student home directories/firststudent'
total 0

chmod

The command you are looking for is chmod. Here a quick hint for your current problem, but I might not harm to do a "man chmod" and read about it in more detail on its manual page! :)

chmod -R o-rx <foldername>

where you do <foldername> for all folders, but Public which you don't want to change. The -R option applies these permission rules to all subfolders and files in those folders.

Maybe it might not harm to try it out on one folder first. It never harms to be safe than sorry.

chmod -R o+rx <foldername>

would give back reading (r) and executing (x) rights.

There is also a number-based short permission version, using 3,2,1 which is basically the decimal of a binary pattern of read, write and execute:

000 disallow all
rwx

111 allow all

for the users, other (o), group (g) and user (u).

More on the man page, or the web. ;)
