Answer:
The Holy Spirit is male because Scripture clearly shows that he is.
He is not gender neutral.
AC 11:15 "As I began to speak, the Holy Spirit came on them as he had come on us at the beginning. 16 Then I remembered what the Lord had said: `John baptized with water, but you will be baptized with the Holy Spirit.' 17 So if God gave them the same gift as he gave us, who believed in the Lord Jesus Christ, who was I to think that I could oppose God?"
AC 28:25 They disagreed among themselves and began to leave after Paul had made this final statement: "The Holy Spirit spoke the truth to your forefathers when he said through Isaiah the prophet:
AC 28:26 " `Go to this people and say,
"You will be ever hearing but never understanding;
you will be ever seeing but never perceiving."
AC 28:27 For this people's heart has become calloused;
they hardly hear with their ears,
and they have closed their eyes.
Otherwise they might see with their eyes,
hear with their ears,
understand with their hearts
and turn, and I would heal them.'
HEB 10:15 The Holy Spirit also testifies to us about this. First he says:
HEB 10:16 "This is the covenant I will make with them
after that time, says the Lord.
I will put my laws in their hearts,
and I will write them on their minds."
HEB 10:17 Then he adds:
"Their sins and lawless acts
I will remember no more."
HEB 10:18 And where these have been forgiven, there is no longer any sacrifice for sin.
