You wrote: “It is impossible that in the eternity God the father gave word the life and authority to judge; and then in incarnation these gifts appear in Son of Man.”
This is an incorrect conclusion, for Jesus Christ is true God and true Man.

1. There was no change in the person for the teaching is that the word “became”, here means
assumed a human nature without change. See Catechism of the Catholic Church
470 Because “human nature was assumed, not absorbed”,97 in the mysterious union of the Incarnation, the Church was led over the course of centuries to confess the full reality of Christ’s human soul, with its operations of intellect and will, and of his human body. In parallel fashion, she had to recall on each occasion that Christ’s human nature belongs, as his own, to the divine person of the Son of God, who assumed it. Everything that Christ is and does in this nature derives from “one of the Trinity”. The Son of God therefore communicates to his humanity his own personal mode of existence in the Trinity. In his soul as in his body, Christ thus expresses humanly the divine ways of the Trinity:98
The Son of God. . . worked with human hands; he thought with a human mind. He acted with a human will, and with a human heart he loved. Born of the Virgin Mary, he has truly been made one of us, like to us in all things except sin.99
2. The Holy Trinity is pure actuality – no potentiality.
You wrote: “Not when we are discussing about Immaterial beings.”
Yes, even when we are discussing immaterial beings. Got is past tense.
You asked: “Is this attribute, Good or Bad or Not good and bad?”
The attributes are good and different yet “It is not a lack of goodness to be a divine person.” means there is nothing bad or lacking in that the persons of the Father, Son, and Holy Spirit, are not identical.
You asked: Why you think Saint Paul refers to creatures?
Divinity does not own anything to divinity.
You wrote: “Possibility of Divinity of 2nd and 3rd persons of Trinity.”
The Holy Trinity is the Christian faith and was declared in the Symbol of Faith from the Church councils.
