EDIT:

Gabber sing: hari modar chod xD = "hari mother fucker."
Prime: BC = "Sister fucker."
Prime: MC = "Mother fucker."

Prime: bc= bhenchod = "sister fucker."
Prime: mc= maderchod = "mother fucker."
Prime: haram zade = "sinful eater/doer." Depends, it can mean either one of those. Not as offencive when it is translated.

Prime: Teri ma ko= "to your mother.." <-- incomplete sentence can be translated into various subjects related to mother but there was no ending.
Gabbar: teri bhi maaka= "even your mother's.." <-- still incomplete but they're trying to reference it to something offensive like saying your mum's.. and stop.
Prime: teri ma ka ni hai be= "your mother does not have it" <-- yes he didn't say anything offensive but it's still referencing.

Gabbar: Meri make pas lund nahi hai = "my mother does not have a dick"
Gabber: teri maaka pata nahi= "no idea about your mother"
Hari: chup betho bhosdi walo = "shut up people who look like you guys are expanded vaginas" <--- bhosdi is a hard word to translate as it means like a vagina that has had loads of ex with multiple partners and has expanded.

Prime: Bharve.= "Pimp" <--- Not a typically good way to translate a bad word but that's what it means. The guy who handles whores. Not a good word the way that word is used.
Gabbar: pencho hari = "ask hari"
Prime: Bharvon ="Pimps"
Prime: Madarchodon = "Mother fuckers."
Prime: Hari ki maa ka = "hari's mother's..." <-- Incomplete again of course, like i've said before they're referencing it in an abusive way.

Hari: Prime laude. = "Prime dick"
Hari: Chakke. = "" <-- no idea
Prime: Bhosra. = "expanded vagina"
Hari: teko kuch bola maa ke laude. ="did i say something to you, your mother's dick" <-- can be referred that your mother has a dick or your her dick. Also that was said to me, so i find either one of those offensive no matter which one it is.
Hari: hijde. "" <-- no idea, this guy was an indian so the language is a bit different.

Hari: Pakistan ki ma ki chut = "Pakistan's mother's pussy"
Gabbar: Hari bad boy bc = "hari bad boy sister fucker"
Prime: Hari bhosre = "hari you're an expanded vagina"
Gabbar: Hari maaki ankh = "Hari, your mother's eye" <-- not offensive but thought it'd be fine to translate it since I accidentally highlighted it.

Prime: hari dehkna pak india ko harey ga next match main = "hari you watch, pakistan will defeat india in the next match" <-- translated that for future reference.
Hari: gand mardenga india pakistan = "india will butt woop pakistan"
Hari: chutyo pkistani = "pussy headed pakistani"

Prime: hari pakistanis sey phati kyun hai? = "Hari why are you so afraid of the pakistanis?"
Hari: phatti to pakistani ki hain india se = "the pakistanis are afraid of the indians"

Hari: isliye chutyo jisa attak karte hain = "that's why they attack like pussy headed people"
Hari: loc pe = "go suck balls"
