Well, you are doing it correctly. You will be required to add and event handler on the <a> tag you have defined. I tried it using jQuery dialog.

Apex Page:

<apex:page controller="ErrorMSG" >
    <apex:pageMessages escape="false" rendered="true" ></apex:pageMessages>
    <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css"/>
    <script src="//code.jquery.com/jquery-1.10.2.js"></script>
    <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
    <link rel="stylesheet" href="/resources/demos/style.css"/>        
    <div id="dialog" title="Basic dialog">
        <p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
    </div>
    <script>
    $j = jQuery.noConflict();
    $j( "#popup" ).click(function(){
        $j( "#dialog" ).dialog();
    })
    </script>
</apex:page>

Controller

public class ErrorMSG {
    public ErrorMSG(){
        ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.WARNING , 'You have received an error <b><u> <span id="popup">Click for Details</span><u></b>'));
    }
}

Result

You will be required to refine the code and surround the dialog by outputpanel and re-render it if there is a failure and hide dialog at start.

The code you've produced is quitting after the first error (return null). A more usual scenario is to set a flag when validation fails, then check for the flag at the end of the validation to abort processing.

Here's a common example:

public PageReference doSomething() {
    Boolean okayToSave = true;
    if( condition1 ) {
        record.field1__c.addError(...);
        okayToSave = false;
    }
    if( condition2 ) {
        record.field2__c.addError(...);
        okayToSave = false;
    }
    if( conditionN ) {
        record.fieldN__c.addError(...);
        okayToSave = false;
    }
    if( !okayToSave ) {
        return null;
    }
    // Now save the data
    insert record;
    return Page.SuccessfulSave;
}

Of course, I left out the part where you use a try-catch block or other error handling for the actual save, because it's not relevant to what I'm trying to explain.

[SalesForce] Odd error: apex:pageMessages not displaying any errors in inline visualforce page. Am i missing something

I suspect the issue here is that the apex:pageMessages tag has been evaluated before your getter is called, so even though you are adding the message correctly to the collection, the rendering engine doesn't take it into account as it has already processed the tag.

As the getter can be called multiple times, it doesn't feel like the best place to be adding a message as you could end up with a long list of duplicates. Looking at the code you are also likely to be making a number of web service callouts. A better way to do this would be to carry out the web service callout from the constructor and setup the cci record there, that way you know it will only happen once and the message will be added before the apex:pagemessages tag is evaluated.
