The Holy Spirit is addressed as a "He" for different reasons in different places in scripture:
Personification....
Genesis 4:10
And he said, What hast thou done? the voice of thy brother's blood crieth unto me from the ground.
Psalm 77:16
The waters saw thee, O God, the waters saw thee; they were afraid: the depths also were troubled.
Isaiah 24:23
Then the moon shall be confounded, and the sun ashamed, when the Lord of hosts shall reign in mount Zion, and in Jerusalem, and before his ancients gloriously.
Joel 1:10
The field is wasted, the land mourneth; for the corn is wasted: the new wine is dried up, the oil languisheth.
Proverbs 8:1
Doth not wisdom cry? and understanding put forth her voice?
Can blood cry? Can water be afraid? Can the sun be ashamed? Can land mourn? Is wisdom female with a voice?
Nobody can survive without spirit, its the lifeforce from The Most High... Therefore spirit is many times used interchangeably with the person controlling it:
Genesis 41:8
8 And it came to pass in the morning that his spirit was troubled; and he sent and called for all the magicians of Egypt, and all the wise men thereof: and Pharaoh told them his dream; but there was none that could interpret them unto Pharaoh.
Samuel 1:15
15 And Hannah answered and said, No, my lord, I am a woman of a sorrowful spirit: I have drunk neither wine nor strong drink, but have poured out my soul before the Lord.
1 Kings 21:4-5
4 And Ahab came into his house heavy and displeased because of the word which Naboth the Jezreelite had spoken to him: for he had said, I will not give thee the inheritance of my fathers. And he laid him down upon his bed, and turned away his face, and would eat no bread.
5 But Jezebel his wife came to him, and said unto him, Why is thy spirit so sad, that thou eatest no bread?
So if I say my spirit is sad, sorrowful, troubled, in grief, etc.... does that mean it is a separate person from me? Of course not. The spirit is part of what makes up a human being. Likewise with the Holy Spirit... which is The Most High's spirit.
Mankind can not see or hear The Most High. He communicates to us through His Spirit. Just like your spirit is not a separate person from you, His spirit is not a separate person from Him. He is the person controlling the spirit, and we experience Him through His Holy spirit.
The last reason The Holy Spirit is sometimes referred to a "He" is simply based on the translator's choice. Many pronouns are universal and could be translated as he, she, it, etc. I do think it makes the most sense to translate the pronouns dealing with the Holy Spirit as "He" though because The Father is the person behind His spirit.
We are never told to worship the Holy Spirit, The Holy Spirit does not have an actual name, no throne in heaven, not mentioned in any of the epistle greetings with the Father and Son, etc. We should be giving The Most High all the glory, rather than share it with His way of interacting with us.
