Offer,

To get 3 items per line, yes, you'd have to manipulate the data before 
feeding it to the template. Into something like,
$names = 
[
 {name1 => name1, name2 => name2, name3 => name3},
 {name4 => name4, name5 => name5, name6 => name6},
];

However, you can print 2 items per line by switching 
on 'loop_context_vars' and doing something like,
<TMPL_LOOP names_loop>
    <TMPL_VAR name> <TMPL_UNLESS __odd__><BR></TMPL_UNLESS>
</TMPL_LOOP>

or to create a table with 2 columns

<table>
    <TMPL_LOOP names_loop>
         <TMPL_IF __odd__><tr></TMPL_IF>
         <td><TMPL_VAR name></td>
         <TMPL_UNLESS __odd__></tr>TMPL_UNLESS>
    </TMPL_LOOP>
</table>
