is it possible to transfer ownership to another address ? Can a token have 2 adrress as owner apart from multisig wallet?
Depends on what you are asking for really.
Owner can be treated as a holder of a token OR the
Owner of the smart contract.
If we just talk about holders:
ERC20tokens can have multiple holders
ERC721token can have one holder per unique ID
ERC1155token can have multiple holders
If we talk about the ownership of the smart contract, then you probably refer to OpenZeppelin's Access Control. That only supports one owner. You could amend that to support more than one though.
