I want to write a launch file for different nodes in different packages. But I don't know where to write it in the catkin_ws.

Generally you put it in a folder launch inside the package where it fits most. You can even create a package only containing your launch file(s) and some config files too (or anything you need).

From here you can see the structure of regular catkin workspace with multiple packages.

workspace_folder/        -- WORKSPACE
  build/                 -- BUILD SPACE
  devel/                 -- DEVEL SPACE
  src/                   -- SOURCE SPACE
    CMakeLists.txt       -- 'Toplevel' CMake file, provided by catkin
    package_1/
      launch/            -- your launch folder
        launch_file.launch  -- your launch file
      CMakeLists.txt     -- CMakeLists.txt file for package_1
      package.xml        -- Package manifest for package_1
    ...
    package_n/
      launch/            -- your launch folder
        launch_file.launch  -- your launch file
      CMakeLists.txt     -- CMakeLists.txt file for package_n
      package.xml        -- Package manifest for package_n
