Answer 1

You can associate the simple products by loading the Configurable product.

Inject the below Class to Construct Method \Magento\Catalog\Model\ProductRepository $productRepository,

So, $this->_productRepository = $productRepository;

Assuming the id of the configurable product as '3' and the simple as ,'1' and '2' respectively.

$associatedProductIds = [2,3];//Simple Product ids array

$configurableProduct = $this->_productRepository->getById(3);

$configurableProduct->setAssociatedProductIds($associatedProductIds);

$configurableProduct->save();

Hope this helps
