James,
You'll want to use array references or something similar:
%hash( james => [ 1, 2 ],
kelty => 3,
biran => 4);
To access the extra values, you'll need to dereference them:
print $hash{james}->[1]; #prints 2
See 'perldoc perlreftut' for a short tutorial on using references.

Someone asked me how to count to 10 in Perl:
push@A,$_ for reverse q.e...q.n.;for(@A){$_=unpack(q|c|,$_);@a=split//;
shift@a;shift@a if $a[$[]eq$[;$_=join q||,@a};print $_,$/for reverse @A
