You are not reading the scripture correctly regarding Ananias and Paul. The Lord said that he may receive his sight in 9:12 not the Holy Spirit or Ghost. It was Ananias that made mention of the Holy Ghost NOT the Lord in verse 17. And after Ananias laid his hands on Paul the scripture says he received his SIGHT, not the Holy Ghost. He was then baptized. See below text. See Acts 9:12 and 9:17
17And Ananias went his way, and entered into the house; and putting his hands on him said, Brother Saul, the Lord, even Jesus, that appeared unto thee in the way as thou camest, hath sent me, that thou mightest receive thy sight, and be filled with the Holy Ghost. 18And immediately there fell from his eyes as it had been scales: and he received sight forthwith, and arose, and was baptized. 19And when he had received meat, he was strengthened. Then was Saul certain days with the disciples which were at Damascus.
What exactly is your objection? Would you agree with me that Paul was filled with the Holy Spirit? Where or not it had anything to do with Ananias' laying hands on Saul/Paul, he received the Spirit apart from the laying on of hands of the twelve apostles.
Paul also wrote to Timothy to lay hands on no man suddenly.
Some time later in Acts 13 we read, "9 Then Saul, who also is called Paul, filled with the Holy Spirit, looked intently at him..." (NKJV). So Paul did receive the Holy Spirit, and since in Galatians, he said that those who seemed to be somewhat added nothing to him, we can conclude that he recieved the Holy Spirit apart from the original 12 apostles. He also healed and recieved Revelations.
There is also no indication in Acts 6-8 that Stephen and Philip performing signs and miracles was connected with the laying of hands of the apostles. Hands were laid on them in connection to the ministry to the widows.
