If your provider is returning to you a Json, then the correct thing is you turn json into an object, so you can interact with it. 

export class AgendaPage {

 users =new Array<any>();//Criando um Array
 cpf: any;

 constructor(public navCtrl: NavController, private buscarProvider: BuscarProvider ){}

logForm() 
{
   this.buscarProvider.buscar(this.cpf)
  .then(
   (result: any) => 
    {
      var result= JSON.parse(result);
      const x = result.success;
      this.users = x;        
    }
 ).catch();
}

As for the on-screen display you can use it in the view: 

<ion-list *ngFor="let user of users">
 <h2>{{user.nome}}</h2>
 </ion-list>
</ion-content>
