uneven haircut

Q: I am a follower of the Hanafi madhab and have great respect for the Hanafi ulema of the sub continent and accept that the answers they give to their question are based only on shariah and there are no ulterior motives, however, I could not come to terms with the answer to the question regarding haircuts.

I understand that scholars give certain answers knowing the intent of the questioner to follow their desires, and they give their answers in such a way that people do not abuse the answer given. However, with regards to the answer on haircuts, the answer mentions that the hair should be kept all one length, however, we are all aware that the prophet and the companions kept long hair up to the earlobes, shoulders and in between and simple reasoning tells me that the hair from the front of the head hanging down to behind the head down to the shoulder would be twice if not three times as long as the hair at the back of the head, therefore, I cannot see a problem with a haircut that is number 5 blade on top and number 4 blade on the side, the difference would not even be noticeable by an onlooker. I am aware of qaza, however, from what I have read this is the complete shaving of hair on some parts and leaving other parts, therefore, can you tell me wether doing a haircut of something along the lines of number 5 on top and number 4 on the sides is haraam or not?

Q: My hair is passed my hips. When I cut my hair when coming out of ihraam, I cut it bent so the end of my hair is uneven. Would it be permissable to straighten it so its 1 length. The purpose is not to imitate kuffar or fashion, because the uneven hair can sometimes look unattractive.

Q: I am a boy. When I go to the barber shop, I ask him to cut my hair short on my sides and the back of my head. But I ask him to keep the front hairs relatively bigger than those at the back. Is it permissible or must all the hairs be cut equal from all sides?

Q: What type of haircut is haraam and which type of hair style is Sunnah?

Q: I have straight hair and it naturally grows longer at the top and front and shorter on the sides. When I get a hair cut I trim all my hair but leave my top and front of the over the forehead less trimmed and the sides a bit more. I don't shave any part of my hair, but just trim unevenly to preserve my hair's natural growth. I also like to part my hair and would like to do something maybe like gel to make it stand a bit. I want to do this to make my hair look bigger and I don't mean to gel it straight up and down, but rather diagonally so it looks like a puffy side part. I don't have an intention to imitate kuffar or do qaza and I've gotten this style from the Middle East and in America. Is this permissible?
