Is obito madara Uchiha

I would think so because Itachi said that Madara Uchiha is alive and Tobi has the Mangekyo Sharingan. Hope this helps :)

In the latest chapter (just came out 2 fridays ago) it was revealed that Tobi is Madara Uchiha. U can read it at onemanga.com

He may be obutto because oubutto had the sharingan that let im teliport like tobi

and obuto got an eye removed and is non with kakashi witch lets him teloport things but not himself, and tobi covers his other eye.

Tobi is not Uchiha Madara. Tobi is not Uchiha Obito. Tobi is not Uchiha Izuna. Tobi is not the eldest son of the Sage of Six Paths. In fact, Tobi is not even someone from the Uchiha clan. All Uchiha are ruled out because the Uchiha clan's chakra nature affinity is Fire Release. Tobi does not even use Fire Release, much less let it be his affinity. If you say the Rinnegan lets him use Fire Release, I will tell you that I am talking about his chakra nature BEFORE the Rinnegan. Tobi uses only Earth Release, which is his affinity. The person who answered this before me is not reading manga from an updated website. if you want updates, read at mangahere.com.

Tobi is also not someone who has been previously granted Jounin rank in Konohagakure. During Naruto's chakra nature training, Kakashi said that to become a Jounin rank shiniobi or kunoichi in Konohagakure, one must first have mastered at least two chakra nature types. Even after obtaining the Rinnegan, we have not seen Tobi use anything but Earth Release Techniques, and Earth release is still his affinity. Plus, Tobi is the only member of Akatsuki other than Zetsu (Kabuto is not an official member) who does not have a forehead protector on. This can only mean one thing. Masashi Kishimoto will be sitting in a room somewhere laughing when we read the next manga and see his obvious answer to Tobi's identity.
