Hello Hosko,
The Iranian visa is not a problem. You can apply and get it from Turkey. You may apply from Istanbul or Ankara and get your visa from Istanbul, Ankara or Erzurum.
The pakistan visa is not possible from Turkey. The embassies in Ankara and Istanbul refuse any application. Many people I hosted in Ankara tried and refused. They say you should get your visa from your home country. Some people I guess was able to get Pakistan visa from Tehran/Iran but I am not sure about it.
As far as I know Indian visa is not a problem either.
Cheers,
Ozgur
