Answer 1

Basically I am not getting your questions. But primarily, it looks like you need stock details.

So, for that, you can follow the below approach

/** @var \Magento\CatalogInventory\Api\StockStatusCriteriaInterfaceFactory $stockStatusCriteriaFactory **/
        $criteria = $stockStatusCriteriaFactory->create();
        $criteria->setProductsFilter($productId);
        /** @var \Magento\CatalogInventory\Api\Data\StockStatusRepositoryInterface $stockStatusRepository **/
        $result = $stockStatusRepository->getList($criteria);
        $stockStatus = current($result->getItems());
        $stockStatus->getProductId();                 // product id
        $stockStatus->getQty();   // quantity of specified product
        $stockStatus->getStockStatus();     // Could be 
// Magento\CatalogInventory\Model\Stock\Status::STATUS_OUT_OF_STOCK = 0;
// or
// Magento\CatalogInventory\Model\Stock\Status::STATUS_IN_STOCK = 1;
