Thanks to a friend, i finally managed to organize my datas.

When you’re creating an array to store your values in a loop, this array doesn’t reset at each loop.
You just have to reset it after each nested loop.

And voilà! You have some custom $cart_object datas, ready to use to modify prices based on whatever you want.
Maybe there is a cleaner way to do it, but for now, it’s working as attended for WordPress 4.9.x/5.x.x and Woocommerce 3.5+.

If it could be usefull for anyone here is the corrected code

add_filter( 'woocommerce_add_cart_item_data', 'woocommunity_custom_cart_item_data', 20, 3 );
function woocommunity_custom_cart_item_data( $cart_item_data, $product_id, $variation_id ) {

//Targeting right product using function parameter
//And counting main loop to organize datas in their matrix
if(have_rows('custom_prices_grids', $product_id)):
$matrice_count = 0;
while(have_rows('custom_prices_grids', $product_id)): the_row();
	
	//General limitation - already good to go
	$var_limits = get_sub_field('custom_prices_variation_limitations');
	$role_limits = get_sub_field('custom_prices_role_limitations');
	
	//Targeting layout - really facultative here as i have a single layout
	if( get_row_layout() == 'custom_prices_grid_details' ):
		
		//Reorder each field in arrays
		while(have_rows('custom_prices_quantity_steps')): the_row();

			$min_qty[] = intval(get_sub_field('custom_prices_quantity_min'));
			$max_qty[] = intval(get_sub_field('custom_prices_quantity_max'));
			$custom_price[] = intval(get_sub_field('custom_prices_qty_new_price'));
			$fixed_price_var[] = intval(get_sub_field('custom_prices_qty_fixed_value'));
			$percent_price_var[] = intval(get_sub_field('custom_prices_qty_percent_value'));
			$var_type[] = get_sub_field('price_type_calculation');
		
		endwhile;
		
		//Storing those fields in their matrice as $cart_item_datas
		$cart_item_data['matrice-'.$matrice_count]['promo_type'] = $var_type;
		$cart_item_data['matrice-'.$matrice_count]['min_qty'] = $min_qty;
		$cart_item_data['matrice-'.$matrice_count]['max_qty'] = $max_qty;
		$cart_item_data['matrice-'.$matrice_count]['new_price'] = $custom_price;
		$cart_item_data['matrice-'.$matrice_count]['fixed_vars'] = $fixed_price_var;
		$cart_item_data['matrice-'.$matrice_count]['percent_vars'] = $percent_price_var;
		$cart_item_data['matrice-'.$matrice_count]['limits_by_var'] = $var_limits;
		$cart_item_data['matrice-'.$matrice_count]['limits_by_role'] = $role_limits;
		
		//Cleaning arrays at each loop
		//Contrary to single values stored - Our arrays don't reset at each loop
		unset($var_type); 
		unset($min_qty); 
		unset($max_qty); 
		unset($custom_price); 
		unset($fixed_price_var); 
		unset($percent_price_var); 
		unset($var_limits); 
		unset($role_limits);
		
	$matrice_count++;
	endif;
	
endwhile; endif;

return $cart_item_data;
