I would say it is highly doubtful Simon was saved
Acts 8:18–24 (LEB) — 18 Now Simon, when he saw that the Spirit was given through the laying on of the apostles’ hands, offered them money, 19 saying, “Give to me also this power, so that whomever I place my hands on may receive the Holy Spirit!” 20 But Peter said to him, “May your silver be destroyed along with you, because you thought you could acquire the gift of God by means of money! 21 You have no part or share in this matter, because your heart is not right before God. 22 Therefore repent of this wickedness of yours, and ask the Lord if perhaps the intent of your heart may be forgiven you!” 23 For I see you are in a state of bitter envy and bound by unrighteousness.” 24 But Simon answered and said, “You pray to the Lord for me so that nothing of what you have said will come upon me.”
In any case none but the Jews had received the Spirit.
The Spirit had yet to be sent to non Jews or half Jews
