I'll talk with to you of about my family...My father have is 45 years old, he is a computer technician in computation, my mother have is 52 years old and she is a housewife, I have two brothers and one sister.

Ten cuidado con la edad, no es como en español (tener) sino que se "es XX años viejo".
Y también intenta separar los enunciados con puntos y no hacer todo una oración grande.
