Having trouble following your logic, but perhaps the following thoughts will help this move along:
(1) The variable "$#" will be the number of parameters supplied. Thus, perhaps no need for the first 3 after your command because you could skip this and then do NumberOfTables="$#"
(2) The shift function allows a script to keep processing references to $1. Thus, you would do your first set of commands and then do a shift. Shift moves what is in $2 to $1, $3 to $2, etc... ; what was in $1 is now gone.
