If you are talking about LoZ:Oot, then to open it, there are two ways:
1. On the 3DS version, you press the ocarina at the bottom left corner of your screen.
2. On the N64 version, you equip it and press the c-pad button its alligned to
To PLAY the ocarina, you just follow the buttons on the screen (you can play any note, but the can only play songs you have unlocked)

Yes. But not without glichting your wii. To play as Tabuu you need the hack system Ocarina. I don't know where or how to download Ocarina. Without Ocarina the answer is no.
at the ocarina store
The amazing thing about Ocarinas is that they don't need to be cleaned. The best thing to do is to is to wipe the blowing opening with a damp cloth. And if spit is being clogged inside the Ocarina, submerge the Ocarina in water (Don't worry, your Ocarina will not be damaged)
the ocarina is one of the oldest instruments to date so there is almost no way to know for sure
Yes in ocarina of time you can skip the fire temple. that's what my friend told me. how it helped :)
