Answer 1

protected $quote;

public function __construct(
    ...
    \Magento\Quote\Model\QuoteFactory $quoteFactory,
    ....
) {
    ....
    $this->quote = $quoteFactory;
    ....
}


$quote = $this->quote->create();

$quote->setData('is_requested', '1');

$quote->save();

Answer 2

 /**
 * @var \Magento\Quote\Model\QuoteRepository
 */
protected $quoteRepository;

/**
 * @param \Magento\Quote\Model\QuoteRepository $quoteRepository
 */
public function __construct(
    \Magento\Quote\Model\QuoteRepository $quoteRepository
) {
    $this->quoteRepository = $quoteRepository;
}

public function updateQuoteData($quoteId, int $customData)
{
    $quote = $this->quoteRepository->get($quoteId); // Get quote by id
    $quote->setData('custom_column', $customData); // Fill data
    $this->quoteRepository->save($quote); // Save quote
}
