The features of quotas are governed totally by UNIX, not by Samba or
shares (or any other such "client"). 

quotas work on the basis of a UNIX partition (i.e. mounted filesystem). 
To achieve a "quota-per-share" model, ensure that the shares for the user
are on different partitions.  That is, in UNIX a user gets one quota per
partition.  So if the user has different directories, but on the same
partition, only one quota is possible.  (Conversely, if his/her
directories are on different partitions, there have to be two separate
quotas; there cannot be one aggregate.)

So initially forget about Samba, shares, PCs etc.  Work out your quota
mechanism for a solely UNIX context.  When (not before) that is done, then
map the Samba stuff onto this.  (And "smb.conf" doesn't come into this at

To assist your users, by the way, configure your samba "--with-quotas": 
that way, the "Properties" of the drive will derive the filespace
attributes from quotas, not from "df".  Actually that raises another
question about whether this ought to be settable per-share, rather than
just the current sledgehammer "per compilation".  But I digress... 

Hope that helps (and hope I got it right!).
