Hi,
You can set topLeft, bottomLeft, topRight, bottomRight promptPosition,also it can be customized.
Please refer below script.
$('#form1').validationEngine(
    'attach', {
        promptPosition : 'topRight:-90,15',
        scroll: false,
        autoHidePrompt: true,
        autoHideDelay: 2500,
        fadeDuration: 0.3,
        focusFirstField : false,
        maxErrorsPerField: 1
    }
);
Make changes in it as per your requirement,I hope this will help you out.
