You are creating custom asset statuses reflecting your company's needs based on the following KB article:
"How to create and use custom Status types for computers" KB 180715
However, you ended up with a large list of asset statuses on your right-click options.
Can we change/rename, delete, or disable some default asset statuses is it possible?
The default ones can't be deleted or renamed (well, they can be deleted/renamed but it requires accessing the database and updating the references directly on the respective tables but that approach is not supported).
About hiding/disabling them, there is not a specific setting/page that does that. You will need to play with Security Roles and remove the permissions for a specific Security Role to those specific menu options.
