try to retrieve the data from SharePoint Online List But its not working

I am using below code to fetch the data from SharePoint online Lists. 

I need to get data from 3 different list on a single page. i create one function LoadAllData to call my 3 functions that contains the actual implementation. 

Right now All 3 functions implementation is same only Lists are Different and  onQuerySucceeded and onQueryFailed i am using Different names for each method. 

when i call only one function any of them working perfect, but when i call 2 or all 3 function then it will run only last function. and it will override the data in div (it will populate the data only from last method)

Below the my code.

$(function () {

    
    SP.SOD.executeFunc('sp.js', 'SP.ClientContext', LoadAllData);
});

 function LoadAllData()
 {    
     GetSliderData();  //Get Data from SliderImages Library
     GetAnnouncements();  // Get Data from Announcements List
     GetAllStaff(); // Get Staff Data From Staff List
 }

function GetSliderData() {
    var clientContext = new SP.ClientContext();
    var oList = clientContext.get_web().get_lists().getByTitle('SliderImages');
    var camlQuery = new SP.CamlQuery();
    this.collListItem = oList.getItems(camlQuery);
    clientContext.load(collListItem);
    clientContext.executeQueryAsync(
    Function.createDelegate(this, this.onQuerySucceeded),
    Function.createDelegate(this, this.onQueryFailed)
    );
}

function onQuerySucceeded(sender, args) {
    var listItemInfo = '';
 var i = 0;
    var listItemEnumerator = collListItem.getEnumerator();
    while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();
        var filename = (oListItem.get_item("FileLeafRef"));       
        var title = (oListItem.get_item("Title"));
        $("#SlideData").append(title + "<br>");
    }
}

function onQueryFailed(sender, args) {

    alert('Request failed. ' + args.get_message() +

    '\n' + args.get_stackTrace());

}


function GetAnnouncements() {
    var clientContext = new SP.ClientContext();
    var oList = clientContext.get_web().get_lists().getByTitle('Announcements');
    var camlQuery = new SP.CamlQuery();
    this.collListItem = oList.getItems(camlQuery);
    clientContext.load(collListItem);
    clientContext.executeQueryAsync(
    Function.createDelegate(this, this.onQuerySucceededAnnouncements),
    Function.createDelegate(this, this.onQueryFailedAnnouncements)
    );
}

function onQuerySucceededAnnouncements(sender, args) {
    var listItemInfo = '';
 var i = 0;
    var listItemEnumerator = collListItem.getEnumerator();
// debugger;
    while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();
                  var title = stripHtml((oListItem.get_item("Title")));
  $("#AnnouncementData").append(title + "<br>");     
    }
}

function onQueryFailedAnnouncements(sender, args) {
    alert('Request failed. ' + args.get_message() +
    '\n' + args.get_stackTrace());
}


function GetAllStaff() {
    var clientContext = new SP.ClientContext();
    var oList = clientContext.get_web().get_lists().getByTitle('StaffRelocation');
    var camlQuery = new SP.CamlQuery();
    this.collListItem = oList.getItems(camlQuery);
    clientContext.load(collListItem)
    clientContext.executeQueryAsync(
    Function.createDelegate(this, this.onQuerySucceededStaffMovement),
    Function.createDelegate(this, this.onQueryFailedStaffMovement)
    );
}

function onQuerySucceededStaffMovement(sender, args) {
    var listItemInfo = '';
    var listItemEnumerator = collListItem.getEnumerator();
    while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();               
                  var title = (oListItem.get_item("Title"));       
                  $("#StaffData").append(title + "br");
    }
}

function onQueryFailedStaffMovement(sender, args) {
        alert('Request failed. ' + args.get_message() +
    '\n' + args.get_stackTrace());
}
