He is our one and only God manifested in the flesh, you may worship whatever God you please, but as for me, I will have no other God before The God of Abraham, and of Isaac and of Jacob and of Moses. There was a commandment about that, and the very fact that there is such a command says there are other Gods...
As I understand it, Mormons believe in multiple gods, and that they can, in fact, become a god themselves some day. That would make them non-Christian.
I believe in multiple Fathers, that does not make them my father, I also believe that I can become a father some day, that does not make my your father.
I can see why you are confused, stick with simpler doctrines.
When you talk about our doctrines, you don't sound clear, and I always think of this song...

I'M MY OWN GRANDPA
Recorded by Lonzo and Oscar on Nov. 1947
Written by M. Jaffe and D. Latham
It sounds funny, I know, but it really is so
Oh, I'm my own grandpa!
CHORUS
I'm my own grandpa
I'm my own grandpa
It sounds funny I know, but it really is so
Oh, I'm my own grandpa.
Now many, many years ago when I was twenty-three
I was married to a (widder) who was pretty as can be
This (widder) had a grown up daughter who had hair of red
My father fell in love with her and soon they two were wed.
This made my dad my son-in-law and changed my very life
My daughter was my mother for she was my father's wife
To complicate the matter even though it brought me joy
I soon became the father of a bouncing baby boy.
My little baby then became a brother-in-law to dad
And so became my uncle though it made me very sad
For if he was my uncle then that also made him brother
Of the (widder's) grown up daughter who of course was my step-mother.
CHORUS
Father's wife then had a son who kept him on the run
And he became my grandchild for he was my daughter's son
My wife is now my mother's mother and it makes me blue
Because although she is my wife, she's my grandmother too.
CHORUS
Now if my wife is my grandmother, then I'm her grandchild
And every time I think of it, it nearly drives me wild
For now I have become the strangest case you ever saw
As husband of my grandmother, I am my own grandpa.
CHORUS
