Is Tibetan Buddhism absolutely forbidden to eat after noon? Is Tibetan Buddhism vegetarian like Buddhism in China? What can and cannot be eaten?

No food after noon means no food after noon. You can drink water and tea instead of milk.

Tibetan Buddhism can eat "clean meat", where there are so many vegetables in plateau areas.

Buddhist disciples at home can eat "clean meat" on days other than October, but not "five spices". It's best to start eating vegan slowly.
