ni2 you3 yi2 ge5 xiong1 di4 huo4 liang3 ge5 xiong1 di4?
However, the correct way to ask a person if they have brothers in Chinese is:
ni2 you3 ge1 ge5 huo4 di4 di5 ma1?
If you would like to know how many brothers they have including older and/or younger brother(s), you would say:
ni2 you3 ji3 ge5 ge1 ge5? ji3 ge5 di4 di5?
Lastly, if you are asking if they have brothers and sisters (older and younger), you would say:
ni2 you3 ji3 ge5 xiong1 di4 jie3 mei4?
*ji3 (how many) ge5 (measure word) = how many
xiong1 = ge1 ge5 = older brother
di4 (di5) = younger brother
jie3 (jie5) = older sister
mei4 (mei5) = younger sister
