Here is the code to show all the subcategories inside an category in magento

<?php
$children = Mage::getModel('catalog/category')->getCategories(10);
foreach ($children as $category) {
    echo $category->getName();
}
?>

Here 10 is the id of the parent category

and to get the url for that category use

<?php
$url=Mage::getModel('catalog/category')->load($category->getId())->getURL();
 ?>

<?php
$imageurl=Mage::getModel('catalog/category')->load($category->getId())->getImageUrl();
?>

Inorder to get the child categories of a category when include in navigation set to no
we have to use the below code to get the children categories

$_categories = Mage::getModel('catalog/category')->load(10)->getChildrenCategories();
foreach ($_categories as $category) {
    echo $category->getName();
}

In this case identifier must be replaced by the one which you created on the admin
