These are all the individual documents describing each small piece of protocol that can be implemented under the LNURL umbrella. Different wallets and services may implement different sets of protocols.

The entire idea of the suite of LNURL protocols is that they are optional. Each new LUD may be implemented by some wallets and not others, some services and not others, but they should still maintain compatibility at all times (except, of course, if the service requires the new functionality).
There is also a hierarchy of internal dependencies between the LUDs -- for example, you cannot implement sending comments in payRequests if you haven't implemented the base payRequest spec also. The following graph displays that hierarchy of internal dependencies (you can safely ignore it though).
Open a pull request with your proposal. Pick the next unreserved number for your proposal. To be accepted, it just has to be generally decent and make sense and be implemented or currently being implemented by 2 or more wallets.
