Custom fields per page
If you are using D6, you need to install the cck module to add custom fields to nodes.

But, if you are using D7, cck has been migrated into drupal core. You can easily create custom fields for each content type at the path admin/structure/types/manage/{content-type-name}/fields. For your page content type, go to admin/structure/types/manage/page/fields.

I think your case is not concerned with the views module. You can generally check what is views here.

AFAIK, there is no module to create different custom fields per node. We can only create custom fields per content type.
If you are sure you have static numbers of page ( such as page, about, etc. ) and if you will not allow your client to add a new page content, it is possible to create and display different fields upon NID.
You will need to write hook_preprocess_field in your theme template.php and hook_form_alter in your custom module to show/hide different field upon NID.
Here are some example code snippet.

In your theme template.php,

function yourtheme_preprocess_field(&amp;$vars){
    $element = $vars['element'];
    // let's say nid=1 is for your home page
    if($element['#object']-&gt;nid == 1){ 
        // hide custom fields for the other node 2
        if( in_array($element['#field_name'], array('field_1_for_nid_2', 'field_2_for_nid_2')) ){
            $vars['classes_array'][] = 'invisible'; // make display:none in theme css file for the class .invisible
        }
    }
    // let's say nid=2 is for your about page
    elseif($element['#object']-&gt;nid == 2){ // do same things for nid=2
        // hide custom fields for the other node 1
        if( in_array($element['#field_name'], array('field_1_for_nid_1', 'field_2_for_nid_1')) ){
            $vars['classes_array'][] = 'invisible'; // make display:none in theme css file for the class .invisible
        }
    }
    // and so on.   
}


In your custom module yourmodule.module,

function yourmodule_form_alter(&amp;$form, &amp;$form_state, $form_id){

    if($form_id == 'page_node_form'){ // for the content type 'page'
        $nid = arg(1);
        if($nid == 1){ // when your client edit the page "home", let's say it is nid=1
            // hide custom fields for the other node 2
            $form['field_1_for_nid_2']['#required'] = FALSE;
            $form['field_1_for_nid_2']['#type'] = 'hidden';

            $form['field_2_for_nid_2']['#required'] = FALSE;
            $form['field_2_for_nid_2']['#type'] = 'hidden';         
        }
        elseif($nid == 2){ // when your client edit the page "about", let's say it is nid=2
            // hide custom fields for the other node 1
            $form['field_1_for_nid_1']['#required'] = FALSE;
            $form['field_1_for_nid_1']['#type'] = 'hidden';

            $form['field_2_for_nid_1']['#required'] = FALSE;
            $form['field_2_for_nid_1']['#type'] = 'hidden';         
        }
        // and so on
    }

}


If you don't know about how to write custom module, here is a good start point.
If you don't want custom coding, the best way is to create different content types with different fields for your pages.
