How tall will I be when I grow up? I am 5'4 my mom is 5'5. I am already taller than both of my older sisters. My dad is 6'0

Depends.... How old are you? What gender are you? If you are a 20 year old, chances are you will be 5'4". If you are a 12 year old, likely you're not done growing.
Can't answer that. This is entirely dependent on knowing your age, sex, stage of puberty, and current height. If you submit this information it will help to address your question.
