$row=mysql_fetch_assoc($sql);
echo $row['name1'].$row['name2'].$row['name3'].$row['name4'];

you need to add limit 1 to ensure only 1 reccord is selected as there could be multiple rows against a single id

$sql=mysql_query("select * from `yourtable` where id='theid' LIMIT 1")or die(mysql_error());
    $row=mysql_fetch_assoc($sql);
    echo $row['name1'].$row['name2'].$row['name3'].$row['name4'];
