Your sample data says you have five fields but your code says you have six fields?   So which is it? 

# then go thorough $hash_F2_2 and that has the key (origin)
# and max as value and make a multivalue hash as follows:

for my $k (sort keys %hash_F2_2){
    my $v = $hash_F2_2{$k};
    #print RESULTS "$k\t$v\n";
    for (my $i=1; $i <= $v; $i++){
        push (@{$hash_F2_3{$k}}, $i);
        # this hash (%hash_F2_3) is the hash of origins and PIPs from 
+1 to max
    }
}

You don't need the inner foreach loop, you can just use the range operator.   And if you remove the loop then you don't need to use push either.   And you don't really need the %hash_F2_2 hash either: 

# then go thorough $hash_F2_1 and that has the key (origin)
# and make a multivalue hash as follows:
my %hash_F2_3;
for my $k ( sort keys %hash_F2_1 ) {
    #print RESULTS "$k\t$hash_F2_1{ $k }\n";
    @{ $hash_F2_3{ $k } } = 1 .. max @{ $hash_F2_1{ $k } };
    # this hash (%hash_F2_3) is the hash of origins and PIPs from 1 to
+ max
    }
