I think you can safely delete the Alemannisch projects as proposed at https://meta.wikimedia.org/wiki/Proposals_for_closing_projects/Deletion_of_A.... In those cases, the projects are being managed as subprojects (namespaces) of Alemannisch Wikipedia, and they have no content. The URLs can be redirected, as suggested on the proposal page.
