Answer 1

Try this :

$order = $this->_objectManager->create('\Magento\Sales\Model\Order')->load($id);
$email = $order->getCustomerEmail();

To get Customer Id :

$customerId = $order->getCustomerId();

Answer 2

Get Customer Id from order details and load your customer and you can get Customer Email.

UPDATE:

$order = $this->_objectManager->create('\Magento\Sales\Model\Order')->load($id);

$customerId = $order->getCustomerId();
