How is bitcoin private key generated?

The bitcoin private key is just a number. You can pick your private keys randomly using just a coin, pencil, and paper: toss a coin 256 times and you have the binary digits of a random private key you can use in a bitcoin wallet. The public key can then be generated from the private key.

Does each Bitcoin have a private key?

Every Bitcoin wallet contains one or more private keys, which are saved in the wallet file. The private keys are mathematically related to all Bitcoin addresses generated for the wallet. Because the private key is the “ticket” that allows someone to spend bitcoins, it is important that these are kept secret and safe.

Can two private keys have same public key?

No, because of how key generation works. A private key is either generated alongside a public key or the public key is derived from the private key using a trapdoor function (this depends on the cryptographic primitive being used).
