No.
Yo soy means "I am"
You have is "Tienes"
The only time I could see this coming into effect is when you are talking about hair color you can say "Soy pelerojo" to mean "I have red hair"
I am who is... maybe trying to say: i am who i am..
"Yo: means "I". Example "Yo" soy de Corea. ["I" am from Korea.]" wrong because soy means i am so you would say soy de corea. you can say yo soy or just soy
es yo or soy yo.
Yo soy or yo estoy
To say it is you: Soy yo.
Yo soy pequeño or Yo soy pequeña for girl
Yo no soy alto (masc) / Yo no soy alta (fem)
Soy linda or Yo soy linda - if you are female Soy guapo or Yo soy guapo - if you are male
I am from... = Yo soy de...
'Yo no soy'
Yo soy puertorriqueño. (if you are a male) Yo soy puertorriqueña. (if you are a female)
Yo soy marroquí
