As far as I can tell these are component licenses for your Horizon 8 Enterprise 100 Concurrent User license. The Horizon license you purchase is a bundle consisting of these components. So if you renew your Horizon 8 Enterprise 100 Concurrent User license-bundle all these sub-licenses will also renew.
The VMware Horizon Packaging and Licensing whitepaper can tell you all the options you have and the rights coming with your specific license.
But these sub-licenses basically allow you to input the correct key for your license bundle when you install the product. E.g. ESXi has a license key, vCenter has a license key, Horizon Connection servers have a license key and so on. There is no 1 universal license key for all the components.
