Hi Rushi,

apex:actionFunction

A component that provides support for invoking controller action methods directly from JavaScript code using an AJAX request. An <apex:actionFunction> component must be a child of an <apex:form> component.

apex:actionPoller

A timer that sends an AJAX request to the server according to a time interval that you specify. Each request can result in a full or partial page update.

apex:actionSupport

A component that adds AJAX support to another component, allowing the component to be refreshed asynchronously by the server when a particular event occurs, such as a button click or mouseover.

apex:actionStatus

A component that displays the status of an AJAX update request. An AJAX request can either be in progress or complete.

apex:actionRegion

An area of a Visualforce page that demarcates which components should be processed by the Force.com server when an AJAX request is generated. Only the components in the body of the <apex:actionRegion> are processed by the server, thereby increasing the performance of the page.

All the corresponding examples you can find from below link:
