Here are a couple of options you might try....

 

 

<apex:page controller="repeaterCon">
    <apex:variable value="{!1}" var="rowNum"/>
    <apex:repeat value="{!collection}" var="row">
        ({!rowNum}){!row}<br/>
        <apex:variable var="rowNum" value="{!rowNum + 1}"/>
    </apex:repeat>
    <apex:dataList value="{!collection}" var="row" type="1">
        {!row}
    </apex:dataList>
</apex:page>
 
 
public class repeaterCon {

    public String[] collection { get; set; }
    
    public repeaterCon() {
        collection = new String[]{'ONE','TWO','THREE'};
    }
}

You could just use a getter in your controller to display the size of the list you're using in the repeat component. For example:
 
Public TestClass {
	
	List<Opportunity> opps = new List<Opportunity>();
	public TestClass() {
		// Code to populate opps
	}

	public Integer getOppsSize() {
		return this.opps.size();
	}

	public List<Opportunity> getOpps() {
		return this.opps;
	}
}
 
Then within your page, reference {!oppsSize} for the number of records in the repeat component and reference {!opps} within the repeat component. Let me know if that helps and answers your question.

But i need counter means after each and every loop or repeater i want show counter Value  as a sequanc. 
 
  <apex:repeat value="{!Opportunies}" var="opp1" first="0" id="theRepeatproduct"> 
      <apex:outputText value="{!opp1.Name}"></apex:outputText>
  <apex:repeat>
 
Output should be like that

The apex:variable technique should work with any component that does iteration - repeat, dataTable, dataList, etc.   I thought I'd throw in the standard use of dataList in case that would be sufficient for your needs.

This worked fine with the repeat and dataList components but now with a dataTable. See this post for more info and my workaround.
