What is the problem with info_all()?

By the way: line 100 is wrong. You must not call delete where you didn't previously called new for.

Actually to remove the person you need a loop on line 98 which goes from the determined index to num_of_people - 1. Thus you may initialize index (line 89) with num_of_people.

I don't get the total amount of people i just get the info of "p1". In line 100 I'm trying to delete the array by using a pointer.

Well, you add

p1 -> r1
p2 -> r2

then you print r1. So just remove r2 and use r1 instead.

In line 100 I'm trying to delete the array by using a pointer.
Yes, that's wrong.
