토니 씨가 언제 시간 있냬요. (If you mean, someone asked you when Mr.Tony has some free time and you say it to the other, you can speak that way and it's pronounced like 인냬요. However, it's a conversational language. We mostly don't write like that. We just write 토니씨가 언제 시간이 되시냐고 하시네요. Also, despite a spoken language, you'd better speak in a formal way like that I've just mentioned when you talk about somebody you call Mr.)
