Answer 1

As your elements are located below 3 levels so you need to use foreach thrice like below:
foreach($data as $items_list){
foreach($items_list[#items] as $items){
foreach($items as $val){
echo $val['nid'];
}
}
}
You can simply count array everytime and add condition before foreach loop to check if further array exists or not.
Like you can count main array and add condition with while loop and then use foreach like below:
$count = 0;
while($count<count($array)){
foreach($array[$count]['#items'] as $items ){
foreach($items as $val){
echo $val['nid'];
}
}
$count = $count+1;
}
Before doing anything, its better if you debug your multiple arrays like below:
echo "<pre>"; print_r($array); die;

Answer 2

You can use a nested foreach to get the final item list from this array object...
foreach($data as $items_list)
{
foreach($items_list[#items] as $items)
{
// do something here....
}
}

Assuming the array structure is exactly as you posted here is something you can experiment with. I don't know what you want to do with each item so this example just prints out the elements of each one:
foreach( $array as $outerarray )
{
foreach( $outerarray['#items'] as $item )
{
echo "{$item['nid']} {$item['changed']} {$item['title']}\n";
}
}
