Hi hart4god,
I believe all the scripture you showed were talking about the spirit that God gives to all people with the first breath of life. All people have this same spirit, it is what gives us life while we are in the flesh, it returns to the Father when we die.
Ecc 3:20 All go to one place; all are of the dust, and all return to dust again.
Ecc 12:7 and the dust returns to the earth as it was, and the spirit returns to God who gave it.
The
Holy Spirit of God is another Spirit of God, that God gives only to the elect at this time.
John 14:15 Jesus said to his disciples: If you love me, you will do as I command.
v.16 Then I will ask the Father to send you the Holy Spirit (Comforter-MKJV, Another Advocate-Rotherham) who will help you and always be with you.
v.17 The Spirit will show you what is true. The people of this world cannot accept the Spirit, because they don't see or know him. But you know the Spirit, who is with you and will keep on living in you. (CEV)
Here is email of Ray's on this subject.

Every person (and animal) has a "spirit." There is no life without spirit. At death OUR spirit return to our God Who gave it to us. Spirit does not die. But, spirit has no consciencousness of its own. It must be united with a body. That is why there is coming a Resurrection of the DEAD. Adam's body had the spirit of God breathed into it and then Adam became a LIVING SOUL. God's Holy Spirit is His Spirit of Holiness which imparts spiritual knowledge and spiritual character to those who possess it. The wicked and unbelievers have a spirit that keeps them alive, but they have no spiritual perception of spiritual truths because they do not possess the Holy Spirit of God living in us through Jesus Christ our Lord. ETc. Sorry, but it would take days to answer your question in detail.
God be with you,
Ray
