Hi Ashritha Reddy,

Please check the below sample code for action poller and action region.
Action Poller Example:

VisualForce page:
  
<apex:page controller="ActionpollarClass">
 <apex:form >
 <apex:pageBlock id="payment">

 <apex:actionPoller action="{!movepayment}" reRender="payment" interval="5" status="status" enabled="{!paymentstate!='complete'}"/>
 <apex:outputPanel id="payment">
 The state of your payment mode is 
 <apex:outputText style="font-weight:bold" value="{!paymentstate}">
 </apex:outputText>
 </apex:outputPanel>
 <br/>
 <apex:actionStatus startText="pooling..." id="status"></apex:actionStatus>
 </apex:pageBlock>
 </apex:form>
</apex:page>

Controller:
  
public with sharing class ActionpollarClass {

    public String complete { get; set; }
    public list<string> states=new list<string>{'Connecting to bank','Authorising','Authotized','complete'};
//index of the currentstate
 private integer stateIdx=0;
//getter to reterive the current state
    public String getPaymentstate() {
        return states[stateIdx];
    }

//action method invoked by the pooer increments the current state index
    public PageReference movepayment() {
    stateIdx++;
        return null;
    }

}
