Answer 1

You just need to make the pass the values to the multiselect as an array:

jQuery(document).ready(function($){
    var users = '3,4,5,6';
    var userarray = users.split(',');

    $("#my_multi_select2").val( userarray );

    console.log( userarray );
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="my_multi_select2" multiple>
    <option value="1">User 1</option>
    <option value="2">User 2</option>
    <option value="3">User 3</option>
    <option value="4">User 4</option>
    <option value="5">User 5</option>
    <option value="6">User 6</option>
    <option value="7">User 7</option>
    <option value="8">User 8</option>
</select>

Per your example:

$.ajax({
    type: 'POST',
    data: ({value:10}),
    url: 'count.php',
    success: function(data){
        var data = jQuery.parseJSON(data);
        console.log(data);
        if( data.status == true ){
            var table   = data.data.row;
            var staffs  = data.staff.STAFF;  //staffs  = [["3"],["2"],["4"],["5"]]
            var users   = staffs.join();     //users   = "3,2,4,5"
            var userArr = users.split(',');  //userArr = ["3", "2", "4", "5"]
            $("#my_multi_select2").val(userArr);
        }
    }
});
