Future forms.

Hi!i would be so pleased if you could answer this,please.

Tour grammar checker has accepted this forms: ´´will having passed my exams,I will not fail the course´´ ´´There will have had been´´ ´´I will have had done my homework´´ could you explain me their uses if possible?Thank you.

And lastly,I´ve read about a pluperfect future tense or double tens.Like this: ´´He will have had run´´ I´d be so grateful if you could answer all my questions!
