You're not showing us any of your input data, but the following certainly works for me:

my $key1 = 'xxx';
my %hash = (
    $key1 => {
        a => 'foo_1_AAAA',
        b => 'foo_1_BBBB',
        c => 'foo_1_CCCC',
    },
);

foreach (sort keys %{$hash{$key1}}) {
    if ($hash{$key1}{$_}=~ /^.+_(\d+)_.+AAA/gi) {
        print "found1\n";
    }
    if ($hash{$key1}{$_}=~ /^.+_(\d+)_.+BBB/gi) {
        print "found2\n";
    }
    if ($hash{$key1}{$_}=~ /^.+_(\d+)_.+CCC/gi) {
        print "found3\n";
    }
}
