If I understand your question correctly, you're trying to get all historic values of a multi-line text field.

The SPServices library makes this quite easy.

$scope.getFieldHistory = function (itemId, fieldName, field) {
            $().SPServices({
                operation: "GetList",
                listName: "Your list name",
                async: false,
                completefunc: function (xData, Status) {
                    var xmlDoc = $.parseXML(xData.responseText);
                    $xml = $(xmlDoc);
                    var list = $xml.find("GetListResult > List");
                    var id = list.attr("ID");

                    $().SPServices({
                        operation: "GetVersionCollection",
                        strlistID: id,
                        strlistItemID: itemId,
                        strFieldName: fieldName,
                        completefunc: function (xData, Status) {
                            var xmlDoc = $.parseXML(xData.responseText);
                            $xml = $(xmlDoc);
                            field.history = [];
                            var values = $xml.find("Versions > Version").each(function () {
                                var version = {};
                                version.value = $(this).attr(fieldName);
                                var rawDate = moment($(this).attr("Modified")).local();
                                version.editDate = rawDate.format("MM/DD/YYYY hh:mm A");
                                var rawEditor = $(this).attr("Editor");
                                version.editor = rawEditor.split("#,#")[1];
                                field.history.push(version);

                            });
                        }
                    });
                }
            });
        };

For getting item's version you do not need any extra hassle. When you request for some items to SP, it returns version along with other data. For example, you have made a GET request to the following URL

_api/web/lists/GetByTitle('List Name')/Items

Now in the response, find __metadata.etag. The value of __metadata.etag is your item's version.

{
  "d": {
    "results": [
      {
        "__metadata": {
          "id": "cf7b1e7a-2103-428a-8e97-7e028ffc9e6a",
          "uri": "https://xxx.sharepoint.com/_api/Web/Lists(guid'233ae45e-f581-4420-b069-b7a74d368b13')/Items(1)",
          "etag": "\"6\"",
          "type": "SP.Data.XXXListItem"
        },
        "Title": "Developer Team"
      }
    ]
  }
}
