apex:ActionFunction: This component helps to envoke AJAX request (Call Controllers method) directly from Javascript method. It must be child of apex:form. Read here – http://www.salesforce.com/us/developer/docs/pages/Content/pages_compref_actionFunction.htm
apex:ActionSupport: This component adds Ajax request to any other Visualforce component. Example : Commandlink button has inbuilt AJAX functionality however few components like OutputPanel does not have inbuilt AJAX capabilities. So with the help of this component, we can enable AJAX.

apex:ActionPoller: This is timer component which can send AJAX request on pre-defined interval. Minimum interval is 5 sec and default is 60 sec
