You need to use jquery .each() function.

Example:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="payment" style="width: 246px;" required multiple="multiple" class="select2" id="id_payment">
  <option value="3" data-name="blago">blago</option>
  <option value="4" data-name="usd" selected>usd</option>
  <option value="5" data-name="uah" selected>uah</option>
  <option value="2" data-name="btc">btc</option>
</select>

<script>
  $(document).ready(function() {
    $('#id_payment :selected').each(function() {
      console.log($(this).data("name"))
    })
    $("#id_payment").click(function(){
      $('#id_payment :selected').each(function() {
        console.log($(this).data("name"))
      })
    })
  })
</script>

It is set up so when you make more selections, it still logs all of the selected items

You can use map to loop thru the selected options and use data to get the data-name values.

var result = $("#id_payment option:selected").map(function() {
  return $(this).data("name");
}).get();

console.log(result);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="payment" style="width: 246px;" required multiple="multiple" class="select2" id="id_payment">
  <option value="3" data-name="blago">blago</option>
  <option value="4" data-name="usd" selected>usd</option>
  <option value="5" data-name="uah" selected>uah</option>
  <option value="2" data-name="btc">btc</option>
</select>

You can use this code

$("#id_payment option:selected").each(function(index, item){

         let name = $(item).data('name');
         //alert(name)
         nameselected.push(name);
         console.log(name);
   })


$(document).ready(function () {
var vals = $('#id_payment').val()
var paymentList = []
var nameselected = []

if (vals) {
    for (var i = 0; i < vals.length; i++) {
        console.log(vals[i])
        paymentList.push($(vals[i]).selector)
    }
  }
  
   $("#id_payment option:selected").each(function(index, item){
         
         let name = $(item).data('name');
         //alert(name)
         nameselected.push(name);
         console.log(name);
   })
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="payment" style="width: 246px;" required multiple="multiple" class="select2" id="id_payment">
        <option value="3" data-name="blago">blago</option>
        <option value="4" data-name="usd" selected>usd</option>
        <option value="5" data-name="uah" selected>uah</option>
        <option value="2" data-name="btc">btc</option>
</select>

Use each to traverse the items and collect them into an array, like:

var dataNames = [];
$("#id_payment > option[selected]").each(function() {
    dataNames.push($(this).data("name"));
});
