Czy teraz jest wszystko okey?

'Will' in the last sentence doesn't have to be backshifted to 'would', neither continuous is that obligatory but necessary in the second one. You can use 'play host to..'

I AM ENJOYING MY HOLIDAY TIME ATTENDING a sports camp with my best friends.
I AM takING part in this camp because I would like to experience something amazing and gain new abilities.
SO FAR, I have ATTENDED all activities, WHICH WERE swimming, basketball and paintball.
Yesterday, we were informed that on Saturday we WOULD HOST a famous BASKETBALL star, but I don't know EXACTLY WHOM.

why 'will' in that sentence doesn't need to be transformed to 'would' ?

The time reference of the statement in the reported piece still applies at the time of the original utterance, right ? The shift is optional.

Even if it is related to such a long time as a few days?

In the sentence 'If I had known I will would be a millionaire in 2021, I wouldn't have agreed to his offer. But today is 2020 and I still don't know if I should regert my former decision.' I heard that will cannot be used as it expresses only hypothesis, not a fact, but IMO the statement refers to the future so the hypothesis can easily turn into the fact in a time being.

So is that right or not?
