The following sentence:
Ça fait cinq minutes que j'attends = I have been waiting for five minutes
is correct .
However 'fait' is always with a 't' in " ça fait, as 'ça'(contraction of 'cela') is an indefinite pronoun like 'it' and is always in the third person singular.
Please beware of "popular translation sites" as they are often wrong....
