Here are a few notable passages (the list is probably not exhaustive - edits are welcome):
13 So if you, despite being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him?” (Luke 11:13 NASB)
14 The grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit, be with you all. (2 Corinthians 13:14 NASB)
26 But the Helper, the Holy Spirit whom the Father will send in My name, He will teach you all things, and remind you of all that I said to you. (John 14:26 NASB)
22 and the Holy Spirit descended upon Him in bodily form like a dove, and a voice came from heaven: “You are My beloved Son, in You I am well pleased.” (Luke 3:22 NASB)
33 Therefore, since He has been exalted at the right hand of God, and has received the promise of the Holy Spirit from the Father, He has poured out this which you both see and hear. (Acts 2:33 NASB)
10 For to us God revealed them through the Spirit; for the Spirit searches all things, even the depths of God. 11 For who among people knows the thoughts of a person except the spirit of the person that is in him? So also the thoughts of God no one knows, except the Spirit of God. 12 Now we have not received the spirit of the world, but the Spirit who is from God, so that we may know the things freely given to us by God. 13 We also speak these things, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual thoughts with spiritual words. (1 Corinthians 2:10-13 NASB)
At face value, these verses appear to be addressing God (the Father) and the Holy Spirit as two separate beings/entities. How do Biblical Unitarians make sense of these and similar passages?
