You can try coriander and parsley which tolerate shade... chervil as well... and I think chives will grow anywhere ! If your rosemary is happy there so thyme should be ok, but buy the whole plants because from seeds it might be to cold. Some cut and come again salads could grow as well, like mizuna or roquette, and also lamb's lettuce....mine are on the shade and they are happy, just a little slower to grow but well...it grows !
