This/these five minutes

In the next five minutes is most natural.

Out of your choices I would say:

In in these five minutes.

Thanks a lot!

Hi Dave,
I agree, but it seems like a year or two back, GG wrote a couple of posts about taking a period of time as a "block," and thereby allowing the singular "this five minutes" as well. I may be wrong.
I think we could say,

I can't find the EF posts, but there are a third of a million Google hits for "this five minutes," about half of them legit.

I would say in this five minute period. Any word that I add to the sentence to mean that I say minute, rather than minutes then I would use this. Plural then these. I'm not saying that I'm right, but that is how I see it.

Thank you all!

How about in casual conversation? Would people avoid using "in this five minutes"?

I would say in this next five minutes.

Or, "in this last five minutes."

I'd be surprised to hear anyone say,
"In these five minutes I've already grown

Hi Avangi,

1. An incident just came into mind. If I am describing a five-minute wait for a report card back in a classroom, for which you are scared that you will flunk the exams. Is "that / those five minutes seems like a long time." correct?

2. I'd like that you correct the grammar in question 1? You could tell me how you would write it?

Thank you.

Is "that / those five minutes seems like a long time." correct?

In my opinion, both are correct. It seems to me to be a case of notional concord. You may choose either one according to how you think of it in your own mind at the time.
I would probably choose "those five minutes," because while I'm waiting, I don't really know
