Answer 1

Please try this,

Add this in your custom controller contructor.

public function __construct(Context $context,\Magento\Framework\App\Request\Http $request){
        $this->request = $request;
        parent::__construct($context);
    }

public function getIddata()
    {
    // use 
        $this->request->getParams(); // all params
        return $this->request->getParam('id');
    }

You can get the param using this $this->getIddata(); in you controller file.
