On a single post, I display the post's categories like this:

  $categories = get_the_category($id);

My category hierarchy is: cat1 parent of cat2, parent of cat3, etc.

I would like to display only children categories (from cat2 to catN). I tried to use get_category_by_slug($id,'cat1') with no results...

For this specific question, Try this

  $categories = get_the_category($id);
  foreach($categories as $category){
        if($category->parent != 0){

         // Display it here
         echo '<a href="' . esc_url( get_category_link( $category->term_id ) ) . '">' . esc_html( $category->name ) . '</a>';

        }
  }
