Apply loop like below:

$.each(applicationTabId, function(key,value){
   console.log(key);
   console.log(value);
});

Based on code you provided now, change your code like below:

function getapplicationlogouturl(applicationTabId) {
    FetchLogoutUrl =  {
        "applicationName": applicationTabId,
    };
    $.ajax({
        type: "POST",
        url: obj.endpoint,
        dataType: "json",
        data: JSON.stringify(FetchLogoutUrl),
        context: document.body,
        success: function (response) {
            if (response != null ) {
                for (var i = 0; i < response.length; i++) {
                    var appName = response[i].name;
                    var tabid = applicationTabId[appName];
                    //print key value data in console to check working fine
                    console.log(appName+'---'+tabid);
                }
            }
        },
    });
}

Note:- var appName and var tabid value will be changed after each iteration happen.
