  2. Hi
    Try to use the get_adjacent_post function according to this link
    http://wordpress.org/support/topic/how-to-get-next-post-id
    you can create a small loop that will get the ID of the next post and then use
    the function again on the ID that you’ve received to get the next next ID.

    $prevPost = get_previous_post();
$i = 0;  
$num_prev_posts = 4;  
while ($i < $num_prev_posts) //needs to check if $prevPost exists. while ($i < $num_prev_posts && !empty($prevPost)) doesn't work. 
{  
    get_permalink($post->ID); //and other such functions that work on the global $post should now work.  
    $i++;  
    $prevPost = get_previous_post(); // and then there should be a check if $prevPost is empty or not  
    print_r($prevPost);  
}

    this will bring the previous 4 posts.

  3. surprisingly,I found the answer myself…

    I am using the same function as I used for next/previous post

    (get_adjacent_post() )
    but sending the the next/previous post which I already found as a parameter

    $in_same_cat = true;

$excluded_categories = '';

$previous = true;

$previous_post = get_adjacent_post($in_same_cat,$excluded_categories,$previous);

$previous_previous_post = 
get_adjacent_post($in_same_cat,$excluded_categories,$previous,$previous_post);

$previous = false;

$next_post = get_adjacent_post($in_same_cat,$excluded_categories,$previous);

$next_next_post = get_adjacent_post($in_same_cat,$excluded_categories,$previous,$next_post);

    but…we haven’t finished yet..
    we need to add this code to the function declaration in wp-includes/link-template.php

    function get_adjacent_post($in_same_cat = false, $excluded_categories = '', $previous = true,$mypost = null) {
    global  $wpdb;

//if specific post wasnt sent to function it takes the global one and checks if its empty before using it.

    if ( empty( $mypost ) )
    {
        global $post;
        if(empty( $post ))
            return null;
        $mypost=$post;
    }
//...
