Answer 1

Here's one way:

Example: http://jsfiddle.net/T6tu4/

$('div.wrapper > a').each(function(i) {
    if( i % 5 == 0 ) {
        $(this).nextAll().andSelf().slice(0,5).wrapAll('
');
    }
});

Here's another way:

Example: http://jsfiddle.net/T6tu4/1/

var a = $('div.wrapper > a');

for( var i = 0; i < a.length; i+=5 ) {
    a.slice(i, i+5).wrapAll('
');
}
