Use These code

$paged = ( get_query_var('page') ) ? get_query_var('page') :1;
$query = new WP_Query( array( 'posts_per_page' => 1,'paged' => $paged,'post_type' => 'achievements','orderby' => 'date', 'order' => 'ASC' ) );
while ( $query->have_posts() ) : $query->the_post();

endwhile;

Instead of

$args = array( 'posts_per_page' => 5, 'post_type'=> 'latestnews');
 $myposts = get_posts( $args );

Your pagination function is only set up for the default main query, not for a custom query.

Also, don't use get_posts for paginated queries. It it is nice function to use for a custom query, but it becomes a bummer to work with once you require pagination.

Rather use WP_Query for paginated queries, it is much easier to use.

Example:

$paged = (get_query_var(‘paged’)) ? get_query_var(‘paged’) :  1;

$args = array(
   'posts_per_page' => 1,
   'paged' => $paged,
   'post_type' => 'YOUR POST TYPE'
);

$q = new WP_Query($args);

if($q->have_post()) {
   while($q->have_posts()) {
     $q->the_post();

     //YOUR LOOP

   }
  //YOUR PAGINATION
}
wp_reset_postdata();

You can have a look at the codex for extra parameters.

You now need to change every instance of $wp_query in your pagination function to $q for it to work.

Just a point of note, you don't have to call the $post global

EDIT

From your comments, there is a much easier way to accomplish your goal without any custom query

This page is an archive page that is meant to display your custom post type latestnews. You can simply just rename your archive-custom.php to archive-latestnews.php. See the Template Hierarchy. Just make sure has_archive is set to true when you register your post type

You should also never shop the main query for a custom query on any type of archive page. It is always troublesome, as you can see. So, delete your custom query and replace it with the default query

This is all you should have in your archive page

if(have_post()) {
   while(have_posts()) {
     the_post();

     //YOUR LOOP

   }
  //YOUR PAGINATION
}

Just change all the instances of $q back to $wp_query again. Everything should work then
