I got solution of how we can use same attribute with different store and websites.

For the we can create our custom source model of an attributes.

<?php

namespace Custom\Module\Model\Eav\Entity\Attribute\Source;
use Magento\Store\Model\StoreManagerInterface;

class FindUs extends \Magento\Eav\Model\Entity\Attribute\Source\AbstractSource
{
    protected $storeManager;
    private $state;


    public function __construct(
        StoreManagerInterface $storeManager,
        \Magento\Framework\App\State $state
    ) {
        $this->storeManager = $storeManager;
        $this->state = $state;
    }

    /**
     * Retrieve all options array
     *
     * @return array
     */
    public function getAllOptions()
    { 
        $storeId = $this->storeManager->getStore()->getStoreId();
        $areaCode = $this->state->getAreaCode();
        $this->_options = array(
                    array(
                    "label" => __("Please select"),
                    "value" =>  0
                )
            );

        if($storeId != 7){
            $this->_options[] =  array("label" => __("Referral"),"value" =>  1);
            $this->_options[] =  array("label" => __("Online Search"),"value" =>  2);
            $this->_options[] =  array("label" => __("Magazine Ads"),"value" =>  3);
            $this->_options[] =  array("label" => __("Walk In"),"value" =>  4);
            $this->_options[] =  array("label" => __("Radio"),"value" =>  5);
            $this->_options[] =  array("label" => __("Newspaper"),"value" =>  6);    
        }
        if($storeId == 7 || $areaCode == 'adminhtml'){
            $this->_options[] =  array("label" => __("ASI"),"value" =>  7); 
            $this->_options[] =  array("label" => __("Newsletter"),"value" =>  8); 
            $this->_options[] =  array("label" => __("Referred by friend/other company"),"value" =>  9);
            $this->_options[] =  array("label" => __("Organic search"),"value" =>  10); 
        }
        return $this->_options;
    }

    /**
     * Retrieve option array
     *
     * @return array
     */
    public function getOptionArray()
    {
        $_options = array();
        foreach ($this->getAllOptions() as $option) {
            $_options[$option["value"]] = $option["label"];
        }
        return $_options;
    }

}

With the help of store manager we can display atribute value store wise.

But in admin all the attribute of value are display for all store.

also, you can create store configuration variable and load accordigly.

If you want to display attribute store wise in admin than you have to create custom javascript.

Thanks,
