Magento 2: How to create multiple custom shipping methods in a single module?

I am referring this (https://www.mageplaza.com/devdocs/magento-2-create-shipping-method/#step-1-declare-a-shipping-module) to create a custom shipping method. But I need to create multiple shipping methods. My doubt is that can we create multiple shipping methods in single module or we have to create separate modules for each.

Can anyone please guide me on this?
