You're storing a string, not a hash reference. A list of lists would be better: 
@FreqListInfoTmp = (
    [ 1, \%HourCalledFreq, "Hours of day calls were made" ],
    [ 2, \%DateFreq, "Dates calls were made" ],
    [ 3, \%CallFreq, "How many callers called how many times" ],
    [ 4, \%DaysOnlineFreq, "How many days callers were online for" ],
    [ 5, \%HoursOnlineFreq, "How many hours callers were online for" ]
+,
    [ 6, \%MinsOnlineFreq, "How many mins callers were online for" ],
    [ 7, \%ClipsVisitedMaster, "How many times which clips were visite
+d" ],
    [ 8, \%CallsMaster, "Detailed info on each caller" ]
);

foreach my $list (@FreqListInfoTmp) {            
    $FreqListInfo{$list->[0]}{NO} = $list->[0];
    $FreqListInfo{$list->[0]}{HASH} = $list->[1];
    $FreqListInfo{$list->[0]}{DESC} = $list->[2];
}

Untested, but if you've read perldsc you'll understand.
