Try:
=COUNTIFS(DIS!B:B,"Taimani",DIS!B:B,"chaman",DIS!B:B,"Khushalkhan",DIS!E:E,"Group Loan",DIS!E:E,"GMRB")

You can't use three criteria arrays (assuming you want all possible combinations) like that. Are there other options in column F that begin with "Trade" that you need to exclude? If not, you could use:

=SUM(COUNTIFS(DIS!B:B,{"Taimani","chaman","Khushalkhan"},DIS!E:E,{"Group Loan";"GMRB"},DIS!F:F,"Trade*"))

Note the semicolons in the second array rather than commas.

Thank you Catalin Bombea but it does not work

Thank you so much Mr Velouria  it is so helpful and if I want to extend my formula such below so could you please fix it to me?

=SUM(COUNTIFS(DIS!B:B,{"Taimani","chaman","Khushalkhan"},DIS!E:E,{"Group Loan";"GMRB"},DIS!F:F,{"Trade","Services","Agriculture"},DIS!C:C,"<200000"))

I don't give out contact info, I'm afraid.

As I mentioned before, you cannot use more than two arrays in a formula like this. I would suggest you use DCOUNT instead. For that you will need a spare couple of cells somewhere for the criteria formula - let's say cells F1 and F2. Leave the first cell (F1) blank, then in the one underneath (F2) enter this formula:

=AND(OR(DIS!B2={"Taimani","chaman","Khushalkhan"}),OR(DIS!E2={"Group Loan","GMRB"}),OR(DIS!F2={"Trade","Services","Agriculture"}),DIS!C2<200000)

and then your count formula becomes simply:

=DCOUNTA(DIS!B:F,1,F1:F2)
