Interestingly none of the tribes you mentioned, are Ghilzais. "Kasuria Pathans" are descendents of Zamands, the Sarabani Afghans. Khakwani or Khugianis are Karlanries. Tareens are Sarabani Afghans. Kakezais are branch of Tarklanries of Saraban division. Niazis are cousins of Ghilzais, but are Lodis.
About
@ghilzai 's comment. These descendents of Afghans in Punjab have always had worked for the interests of their parent Pashtun qaum of Afghanistan/Pakhtunkhwa before the Sikh period, at the cost of their own destruction, they were qaum-parast. They owed their power and Jagirs to Mughals, but as soon as Afghan Kings appeared on the scene in 18th century, they gave up on the former and shifted their allegiance to their Kinsmen from Afghanistan. They were the only ones in Punjab, on whom Ahmad Shah Abdali and his successors relied against Sikhs, so when Afghan rule dwindled in Punjab, they suffered greatly at the hands of Sikhs. The ancestors of these Punjabized Pathans have great shares in Pashtun history, but things are different nowadays, they are no longer qaum-parast.
