Answer 1

$category = Mage::getModel('catalog/category')->load($id);

$catnames = array();
foreach ($category->getParentCategories() as $parent) {
    $catnames[] = $parent->getName();
}

Answer 2

Simplest way without loads in loops:

$category = Mage::getModel('catalog/category')->load($categoryId());
$names = array();
foreach ($category->getParentCategories() as $parent) {
    $names[] = $parent->getName();
}
//do what you need with `$names` array

Answer 3

<?php
    // get current path
    $path = $this->getCurrentCategory()->getPath();

    // explode path
    $ids = explode('/', $path);

    foreach($ids as $id) {

        $cat = Mage::getModel('catalog/category')->setStoreId(Mage::app()->getStore()->getId())->load($id);
        $catName = $cat->getName();

        echo $catName;

    }

?>

If you use the function getParentCategories() then it called the function

load() which is taken more load time. See:

$pathIds = array_reverse(explode(',', $category->getPathInStore()));
        $categories = Mage::getResourceModel('catalog/category_collection')
            ->setStore(Mage::app()->getStore())
            ->addAttributeToSelect('name')
            ->addAttributeToSelect('url_key')
            ->addFieldToFilter('entity_id', array('in' => $pathIds))
            ->addFieldToFilter('is_active', 1)
            ->load()
            ->getItems();

Then it will better to call Custom Category collection and doesnot use collection load function .

$category = Mage::getModel('catalog/category')->load($id);
 $catnames=array();
$pathIds = array_reverse(explode(',', $category->getPathInStore()));
$Categories = Mage::getResourceModel('catalog/category_collection')
            ->setStore(Mage::app()->getStore())
            ->addAttributeToSelect('name')
            ->addFieldToFilter('entity_id', array('in' => $pathIds))
            ->addFieldToFilter('is_active', 1);


foreach ($Categories as $Eachparent) {
    $catnames[] = $Eachparent>getName();
}
