Your approach to writing these two-in-one questions is correct. You write the first question, add a comma and "or" and then ask the second one with a question mark at the end. Multiple options can be separated with commas.
Yes, it's written correctly. I'm not sure what you think could be incorrect, though. If you're worried about the usage of the comma before "or", your usage is correct.
What you're doing here is combining two questions or two independent clauses with a coordinating conjunction, which conjoins two or syntactically identical units. The comma before the conjunction (when dealing with two clauses) is stylistic and optional, though I'd personally recommend it.
Your examples look perfect.
