How to write Cheng Ge's English name?

The English name translation of "Cheng Ge" is the same as pinyin:

Cheng, Ge (in English grammar, commas are used to distinguish surnames from first names)

Generally speaking, self-introduction is to call "brother" first, and then call "Cheng":

Ge Cheng (when the first name is written before the last name, no comma is needed).

If you want to find another homophonic English name, you can consider: Gordon, Gonzo.

If "Cheng Ge" is a respectful name, people will not call it "Brother XXX" in general English, but friends will say "Hello, Brother?" How are you, brother? )
