I think this will work for what you are asking for (I changed the names of the arrays to make it more descriptive as to what was going on):

#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

my @keys = qw(a b c d e f g);
my @numbers = qw(1 2 3 4 5 6 7);
my @animals = qw(aardvark bird cat dog elephant fish goat);
my @boys = qw(andy bart charles david elmer fred george);
my @girls = qw(anna bertha charlize daphne ellen frida gina);

my %hash = map { 
  $keys[$_] => { 
    numbers => $numbers[$_],
    animals => $animals[$_],
    boys    => $boys[$_],
    girls   => $girls[$_]
  } } 0 .. $#keys;

print Dumper \%hash;
