Hi @TeguhDiyanto Welcome to the instructor's community!
1. Yes, you are able to teach in Udemy as one company. You can use your name or the company name.
2. If you are referring to having more than one content creator, yes you are able to add them as co-instructors or teaching assistants. You can take a look at these two support articles about Co-Instructor Relationships: Rules and Guidelines and Adding Co-Instructors and Assistants They both have useful information about the permissions you can grant to a co-instructor and the steps to do so.
I hope this information helps!
