Hey, I'm just having trouble finding out why they would use what they used in this sentence

"Директор ушёл и сегодня его не будет" Why его instead of он?

And also, I'm confused when to use пойти and уйти. My book says пойти is used for leaving for a known goal (Он пошёл домой) and can't be referred to the place being left, unlike уйти. Now can someone give me some examples on the differences?

As well as "Кто к вам приходил после собрания." I understand that someone arrived after the meeting, but where does the к вам come into place?

And in this exercise (my own answers are in the parentheses)... Вчера к нам в гости (приезжал) Олег, он (ушёл) с собой своего внука. Why do they use the reflective/possesive so much? Cобой своего внука seems redundant.

And thank you for listening to me.
