Greece, Peloponnese, Agios Ilias Beach. Limestone. I spent a long and painful search on the Internet for geological maps of Greece.... Most of them show Quaternary (Holocene or Pleistocene) deposits at this location. On some - Neogene.
Portugal, Praia das Maçãs. Limestones, sandstones, marls and dolomites. Cretaceous. Upper Aptian, Albian, Cenomanian, Turonian. In the third photo - I do not know what it is. Basaltic lava maybe?
Upper Jurassic succession of Easern Sardinia. Bioclastic limestones, oolitic cherty limestones and mudstones, of littoral-cricalittoral environment, with algae, benthic foraminifer and nerineids. Alternatively: Dogger-Malm.
