You are building a key with $3 and $4 where there exists only fields $1 $2 $3 with an unaltered field separator.

If I understood it correct, you might want something like this?
Code:
$ awk '{a[$2 FS $3]++; b[$2 FS $3]=$1} END{for(e in a){if(a[e] > 1){print a[e], b[e], e}}}' infile| sort -r
3 0.910094 Aahan Aabid
3 0.893134 Aahva Aaban
3 0.810667 Aaditya Aadhan
3 0.491736 Aagneya Aadam
3 0.484934 Aadvik Aadavan
3 0.366954 Aagney Aadan
3 0.265232 Aahlaad Aabheer
3 0.193443 Aaditeya Aadhira
3 0.173545 Aadrian Aadesh
3 0.151862 Aagam Aadarsh
2 0.845814 Aadinath Aadil
2 0.585537 Aadit Aadi
2 0.291066 Aadil Aadinath
2 0.152208 Aadir Aadidev

I am not sure if it makes sense to process $1 this way, since for example "Aahan Aabid" has 3 entries with 2 different numbers in front. If $1 makes a difference and needs to be printed, you might include $1 into the key instead of using it in a second array.

Name
       makedbm - make a yellow pages dbm file

Syntax
       makedbm [ -i yp_input_file ] [ -o yp_output_name ] [ -d yp_domain_name ] [ -m yp_master_name ] infile outfile
       makedbm [ -u dbmfilename ]

Description
       The command takes the file specified by the argument infile and converts it to a pair of files in format, namely and Each line of the input
       file is converted to a single record.  All characters up to the first tab or space form the key, and the rest of the line is defined as the
       key's  associated data.	If a line ends with a backslash (), the data for that record is continued onto the next line.	It is left for the
       clients of the yellow pages to interpret the number sign (#); does not treat it as a comment character.	The  infile  parameter	can  be  a
       hyphen (-), in which case reads the standard input.

       The  command  is  meant	to  be	used in generating files for the yellow pages service.	The command generates a special entry with the key
       yp_last_modified, which is the date of infile.

Options
       -i     Create a special entry with the key yp_input_file.

       -o     Create a special entry with the key yp_output_name.

       -d     Create a special entry with the key yp_domain_name.

       -m     Create a special entry with the key yp_master_name.  If no master host name is specified, yp_master_name will be set  to	the  local
	      host name.

       -u     Undo a file.  That is, print out a file one entry per line, with a single space separating keys from values.

Examples
       The  following  example shows how a combination of commands can be used to make the yellow pages files and from the file.  The percent sign
       (%) signifies the system prompt.

       % awk 'BEGIN { FS = ":"; OFS = ""; }
	{ print $1, $0 }' /etc/passwd > ptmp
       % makedbm ptmp passwd.byname
       % rm ptmp

       The command creates the file ptmp which is in a form usable by The command uses the ptmp file to create the yellow pages dbm files and  The
       command removes the ptmp file.
