When can I apply for a new passport when I am arrested and my passport is cut off?

I'm an immigration officer, and it should be an international practice to cut the corners of my passport, which means your passport is invalid. You only need to take this old passport to the exit-entry administration department of the Public Security Bureau to apply for a new passport, which is no trouble at all. The punishment your friend received when he was sent back to China will not affect his passport application in the future.
