What do the Nicene, Apostles, Chalcedonian, Creeds add to the concept of God, Jesus, and the Holy Ghost that is not found directly in the Bible?

The biggest thing about these councils specifically is the addition of God being three persons, which "persons" were to be included in the term "God", and the evolution of such. For example, the Apostle's Creed which pre-dates the first of these councils (Nicea) says nothing about God being more than one nor anything about multiple "persons" being "God".

Apostle's Creed

I believe in God the Father Almighty, Maker of heaven and earth: And in Jesus Christ his only Son our Lord, Who was conceived by the Holy Ghost, Born of the Virgin Mary, Suffered under Pontius Pilate, Was crucified, dead, and buried: He descended into hell; The third day he rose again from the dead; He ascended into heaven, And sitteth on the right hand of God the Father Almighty; From thence he shall come to judge the quick and the dead. I believe in the Holy Ghost; The holy Catholick Church; The Communion of Saints; The Forgiveness of sins; The Resurrection of the body, And the Life everlasting. Amen.

However, the Council of Nicea took it a step further by making God and Jesus as "persons" of "God", but not the Holy Spirit. The Holy Spirit in the original Nicene Creed was simply tacked on the end so as to be included. Observe:

Original Nicene Creed

We believe in one God, the Father Almighty, Maker of all things visible and invisible. And in one Lord Jesus Christ, the Son of God, begotten of the Father [the only-begotten; that is, of the essence of the Father, God of God], Light of Light, very God of very God, begotten, not made, being of one substance with the Father; By whom all things were made [both in heaven and on earth]; Who for us men, and for our salvation, came down and was incarnate and was made man; He suffered, and the third day he rose again, ascended into heaven; From thence he shall come to judge the quick and the dead. And in the Holy Ghost.

This creed was later modified at the council of Constantinople to include the "person" of the Holy Spirit as "God".

Modified Nicene Creed From The Council Of Constantinople

We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible. And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds (æons), Light of Light, very God of very God, begotten, not made, being of one substance with the Father; by whom all things were made; who for us men, and for our salvation, came down from heaven, and was incarnate by the Holy Ghost of the Virgin Mary, and was made man; he was crucified for us under Pontius Pilate, and suffered, and was buried, and the third day he rose again, according to the Scriptures, and ascended into heaven, and sitteth on the right hand of the Father; from thence he shall come again, with glory, to judge the quick and the dead; whose kingdom shall have no end. And in the Holy Ghost, the Lord and Giver of life, who proceedeth from the Father, who with the Father and the Son together is worshiped and glorified, who spake by the prophets. In one holy catholic and apostolic Church; we acknowledge one baptism for the remission of sins; we look for the resurrection of the dead, and the life of the world to come. Amen.

The evolution continued with the Council of Chalcedon when the "dual nature" was discussed, hammered out, and added.

Confession of Chalcedon

We, then, following the holy Fathers, all with one consent, teach people to confess one and the same Son, our Lord Jesus Christ, the same perfect in Godhead and also perfect in manhood; truly God and truly man, of a reasonable [rational] soul and body; consubstantial [co-essential] with the Father according to the Godhead, and consubstantial with us according to the Manhood; in all things like unto us, without sin; begotten before all ages of the Father according to the Godhead, and in these latter days, for us and for our salvation, born of the Virgin Mary, the Mother of God, according to the Manhood; one and the same Christ, Son, Lord, only begotten, to be acknowledged in two natures, inconfusedly, unchangeably, indivisibly, inseparably; (ἐν δύο φύσεσιν ἀσυγχύτως, ἀτρέπτως, ἀδιαιρέτως, ἀχωρίστως – in duabus naturis inconfuse, immutabiliter, indivise, inseparabiliter) the distinction of natures being by no means taken away by the union, but rather the property of each nature being preserved, and concurring in one Person (prosopon) and one Subsistence (hypostasis), not parted or divided into two persons, but one and the same Son, and only begotten God (μονογενῆ Θεόν), the Word, the Lord Jesus Christ; as the prophets from the beginning [have declared] concerning Him, and the Lord Jesus Christ Himself has taught us, and the Creed of the holy Fathers has handed down to us.

So in summary directly related to the original question:

1. The Apostle's creed really doesn't add much to what we already find in scripture
2. The Original Nicene creed adds Jesus to the godhead to what we find in scripture
3. The modified Nicene creed adds the Holy Spirit to the godhead to what we find in scripture
4. The Chalcedonian creed or Confession of Chalcedon adds the dual nature to what we find in scripture
