        $(".addLabel").append("<label class="
            addLabel2 ">" + j + "</label>"); //children loop in parent class
    }

Answer 1

First of all, your text has too many mistakes and it's hard to understand what exactly is the problem.

Secondly - your string in append() function is not concatenated properly as addLabel doesn't seem to be a variable. Try this:

$(parentdiv).append("<label class='addLabel"+ i +"'></label>") and
$(".addLabel").append("<label class='addLabel"+ j +"'></label>");

Answer 2

The problem solved the children loop :

//children loop start
for (var c = 0; c < checkBoxs.length; c++) {
    // Things[i]                
    console.log(c);
    var multiInputs = $("#myframe1").contents().find(".div2");  // iframe parent div
    var putIntoParent = $(multiInputs).children(); // selector as parent children
    var getMultiInput = multiInputs.selector;
    //$(multiInputs).append('<lable><input type="checkbox"/>'+ checkBoxs[c].label +' </label>');
    var node = document.createElement('span');
    //var inputPlace = document.querySelector('.inputField_add');
    console.log(multiInputs)
    // $(multiInputs).on("load", function() {
    $(putIntoParent).append('<lable><input type="checkbox"/>'+ checkBoxs[c].label +' </label>');
    // });                  
}
