Is it permissible to say: (I repent to Allah and His Messenger), (I entrust you to Allah and His Messenger), and (Allah and the Prophet are sufficient for us)?

Repentance, turning to God, and relying on Him for sufficiency and provision are exclusively for Allah alone. It is not permissible to associate anyone else with Him in these matters, such as saying, "I repent to Allah and the Messenger," or "Allah and the Prophet are sufficient for us," or "I entrust you to Allah and His Messenger." Indeed, sufficiency and provision, like reliance, piety, and worship, are for Allah alone.
