With an awk script that long it's hard to tell what you're doing.

If all you really want to do is count uses of the first column:

Code:
BEGIN { FS=";" }

{        if(length($0) > 0)
                count[$1]++;
}

END {
        for(keys in count)
                print keys ":" count[keys];
}

For your input data, this prints:
Code:
Zain500Disc:1
ZainEazy:1
ZainQuattro:1
Jaishana:1

It's hard to "optimize" huge amounts of logic since the slowdown may not be in one important place but in the logic itself. "optimizing" it means pretty much replacing it. Here I would use sort:

Code:
BEGIN { FS=";" ; count=1 ; cur=""; }

{
        if(length($0) > 0)
        {
                if(cur == $1)   count++;
                else
                {
                        if(length(cur) > 0)
                                print cur " had " count "\n";

                        cur=$1;         count=1;
                }

                print $0;
        }
}

END {   if(length(cur) > 0)     print cur " had " count "\n";   }

Code:
sort < input | awk -f count.awk

That way, you get your records already grouped and just have to count when things change.

xkbfreegeomoverlaykeys

XkbFreeGeomOverlayKeys(3)					   XKB FUNCTIONS					 XkbFreeGeomOverlayKeys(3)

NAME

       XkbFreeGeomOverlayKeys - Free keys in an overlay row

SYNOPSIS

       void XkbFreeGeomOverlayKeys (XkbRowPtr row, int first, int count, Bool free_all);

ARGUMENTS

       - row  row in which keys should be freed

       - first
	      first key to be freed

       - count
	      number of keys to be freed

       - free_all
	      True => all keys are freed

DESCRIPTION

       Xkb  provides a number of functions to allocate and free subcomponents of a keyboard geometry. Use these functions to create or modify key-
       board geometries.  Note that these functions merely allocate space for the new element(s), and it is up	to  you  to  fill  in  the  values
       explicitly  in  your  code. These allocation functions increase sz_* but never touch num_* (unless there is an allocation failure, in which
       case they reset both sz_* and num_* to zero). These functions return Success if they succeed, BadAlloc if they are  not	able  to  allocate
       space, or BadValue if a parameter is not as expected.

       If  free_all  is True, all keys are freed regardless of the value of first and count.  Otherwise, the number of keys specified by count are
       freed, beginning with the key specified by first in the specified row.

RETURN VALUES

       Success	      The XkbFreeGeomOverlayKeys function returns Success if there are no allocation or argument errors.

DIAGNOSTICS

       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
