How to override zend classes like vendor/magento/zendframework1/library/Zend/Validate/Hostname.php

[Ravikant soni]

Hi Mage Experts,

I want to override below classes in magento2. 

vendor/magento/zendframework1/library/Zend/Locale/Data/de.xml
vendor/magento/zendframework1/library/Zend/Validate/Hostname.php
vendor/magento/zendframework1/library/Zend/Currency.php
vendor/zendframework/zend-validator/src/Hostname.php

Is there a way so I can make changes in functions of these classes ?
