You’ve been given clear answers, and I’ll chip in with:
Statistics from the Catholic Mission Project:
catholicmission.org.au/projects
Also, Fr. Ernesto Cagnacci also began this new mission in Kabul.
And
There are already Catholics in each country you listed.
Pakistan: “There are over one million Catholics in Pakistan, which represents less than 1% of the total population. There are 7 ecclesiastical units in Pakistan comprising 2 archdioceses, 4 dioceses, and one Apostolic Vicariate, all Latin Rite.
The Catholic Church in Pakistan is also active in education managing leading schools…”
Iraq:
"There are over 300,000 Catholics living in Iraq, just 0.95% of the total population. The Catholics of Iraq follow several different rites, but most are members of the Chaldean Catholic Church. There are 17 currently active dioceses and eparchies in Iraq."
Afghanistan: " There are very few Catholics in this overwhelmingly Muslim country — just over 200 attend mass in its only chapel — and freedom of religion has been difficult to obtain in recent times, especially under the former Taliban regime."

Glad that I could help you to Google facts. With a.little perseverance, you can get the hang of looking up answers to such challenging questions all by yourself.
Now, would you kindly stop hijacking multiple threads with the same questions and open your own?
