How can I know from which form id a given function is sent? The function is buscar_cidades() and is present in 2 forms Pessoa Física and Pessoa Jurídica .

How to know in jQuery which form (id) the function is being sent to? 

<form action="" id="pessoa_fisica">
    <select name="estado" onchange="buscar_cidades()">
       ...
    </select>
</form>

<form action="" id="pessoa_juridica">
    <select name="estado" onchange="buscar_cidades()">
       ...
    </select>
</form>
  

Update

Knowing which id is being sent to the function, how to capture the select of this id knowing that the select has class estado ? 

  var formid = $(e).closest("form").attr("id");
  var estado = ??????????

In JavaScript you can pass this to your function that is called in the change event so that within it you can know which element used it.

With jQuery you can then convert to an object, upload to form and collapse id :

Example in JSFiddle 

function buscar_cidades(e) {
    var formId = $(e).closest("form").attr("id");
    alert(formId);
}

For a JavaScript-only solution, you can: 

function buscar_cidades(e) {
    var formId = e.form.getAttribute("id");
    alert(formId);
}
