The visions of the city come after the youngest turns 17, while the powers come to each individually when the person themself turns 17.

[@McHaggis] I'll try to reword it so it's a little more clear, but yes. As soon as any one of them turned 17, they're powers kicked in. This is mainly to add some diversity of skill amongst the group. Obviously, the older the character the more experienced they are with their abilities and vice versa.
