Answer 1

Please create module and add below code in Block file.

<?php
namespace Vendor\CustomerGroup\Block;

class CustomerGroup extends \Magento\Framework\View\Element\Template
{
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Customer\Model\ResourceModel\Group\CollectionFactory $groupCollectionFactory,
        array $data = []
    ) {
        $this->groupCollectionFactory = $groupCollectionFactory;
        parent::__construct($context, $data);
    }

    /**
     * Retrieve customer group collection
     *
     * @return GroupCollection
     */
    public function getCustomerGroupCollection()
    {
        if (!$this->hasData('customer_group_collection')) {
            $collection = $this->groupCollectionFactory->create();
            $this->setData('customer_group_collection', $collection);
        }

        return $this->getData('customer_group_collection');
    }

And then you can get customer group data in template file

<?php
$customerGroupCollection = $block->getCustomerGroupCollection();
foreach($customerGroupCollection as $customerGroup) {
    echo 'ID '.$customerGroup->getId();
    echo 'Code '.$customerGroup->getCode();
    echo 'Tax class Id '.$customerGroup->getTaxClassId();
    echo "<br>";
}

Hope it will work for you
