Example in post loop,
New post (newest posting)
-> field A
-> field B
-> field X (from older post)
-> field Y (from older post)

Older post
-> field X
-> field Y

Other post
-> …
-> …

I’m not completely sure what you’re trying to do, so I’m assuming some things.

<?php 
  $count = 0; // keep track of how many posts were shown
  // the standard WP loop
  if (have_posts()) {
    while(have_psits()) {
      the_post();
      $count++; increment count
      if ($count == 1) {
        // showing first post
        // code here to show fields A & B
      } else {
        // showing older posts
        // code here to show fields x & y
      }
    }
  }
?>

– custom field Y_2 (key_x_2)
– custom field Z_3 (key_x_3)

———-

Post 3 (category Tech)

This won’t be possible with just ACF. You’re going to need to do some custom queries in WP.

For each post you’re going to need to do a query to get the next post from the same category and then show the fields from that post. I would suggest that you take a look at http://codex.wordpress.org/Class_Reference/WP_Query

can you give sample code?

The best I can do here would be pseudo code. This forum is really for helping with questions about ACF and what you need is help with basic WP queries and loops. It would be large project for me to code everything that you need here.

// this would be the main loop in your template
while(have_posts)) {
  the_post();
  // show the fields for this post
  /*
        get the category of this post - wp_get_post_terms()
        get the date of this post - get_the_date()
        do a WP_Query to get the next older post in same category
        new WP_Query() with tax and date queries to get one post
        Nested post loop to loop over secondary query and show fields
  */
  
}
