The Dalai Lama and Simeon II of Bulgaria were both heads of state during WW II. But China invaded Tibet in 1950, and by 1960 the Dalai Lama ruled nothing. And Simeon lost his throne in 1946 (though he did get elected prime minister many years later).

I wouldn't count them as monarchs any more.
That said, looking at https://en.wikipedia.org/wiki/List_of_current_monarchs_of_so... I find the following currently reigning monarchs who were born before WW II and probably remember something from it:
- Emir Nawaf Al-Ahmad Al-Jaber Al-Sabah of Kuwait
- King Harald V of Norway
- King Salman of Saudi Arabia
- Pope Francis of Vatican State
