To get the attributes of the DIV is very simple, because the DOM instance of each DIV is retrieved by the ui.item object that comes as a parameter of the event, which in turn is a jQuery object so its attributes can be accessed by methods of jQuery (.attr () .data () and etc.)
An example:
update: function(event, ui){
var element = ui.item;
console.log(element.text());
}

I have achieved, the code can be seen below:
$(function() {
$("#conteudo").sortable({
axis: 'y',
handle : ".ico",
start: function(event, ui) {
ui.item.startPos = ui.item.index();
},
update: function(event, ui){
console.log("Posição inicial: " + ui.item.startPos + " Nova posição: " + ui.item.index());
// Atualizando index para o usuário...
// Obtendo todos os itens:
var itens = $(this).children();
console.log("Quantidade de itens: " + itens.length);
// Atualizando valor em cada item:
itens.each(function(){
var item = $(this).children();
console.log("Quantidade de filhos: " + item.length);
var newVal = $(this).index() + 1;
$(item).children('.index').html(newVal);
});
console.log("***********************************");
}
});
$("#conteudo").disableSelection();
});.item { width: 100%; height: 90px; border: 1px solid black;}
.item:hover {
border: 3px solid black;
}
#conteudo { width: 95%; height:500px; border:2px solid #ccc; padding: 10px; }
.ico {
float: left;
width: 3%;
border: 2px solid #fff000;
cursor: move;
}
.conteudoItem{
float: left;
width: 90%;
