Answer 1

In your block constructor inject

\Magento\SalesRule\Model\ResourceModel\Rule\CollectionFactory $salesRuleCollectionFactory,

and then filter the sales rules collection by customer group id

$_salesRulecollectionByCustomerGroup = $this->_salesRuleCollectionFactory->create()->addCustomerGroupFilter($currentGroupId);

Answer 2

Please add this code in your file. Youo will get what you want

$currentGroupId = $this->_customerSession->getCustomer()->getGroupId(); 
    $_salesRulecollectionByCustomerGroup = $this->_salesRuleCollectionFactory->create()->addCustomerGroupFilter($currentGroupId);
    $collection = $this->_customerGroupCollection->load($currentGroupId);
    $result=$_salesRulecollectionByCustomerGroup->getData();
    foreach ($result as $res) {
        print_r($res['rule_id']);

    }

And Customize it according to your code.
