Laravel - Model BelongsTo multiple models - php

Question

I am developing a system and I have a question, in the system I have 3 main models (User, State, City), to manage the users I use a package for Laravel called Entrust, with this package I can define system roles, one of these roles is the manager, the manager can have Cities and States, however, a States can have several Cities, so in my model Cities BelongsTo to a User and a States.
Is that correct? A model can BelongsTo more then one model? I found no satisfactory answer on Google.
User.php
class User extends Authenticatable
{
use Notifiable;
use EntrustUserTrait;
use SearchableTrait;
protected $fillable = [
'role',
'active',
'status',
'name',
'slug',
'email',
'password',
'cpf',
'rg',
'mothers_name',
'marital_status',
'curriculum',
'psychiatric_report',
'contract',
'phone',
'adress',
'city',
'state',
'country',
];
protected $hidden = [
'password', 'remember_token',
];
protected $searchable = [
'columns' => [
'users.name' => 10,
'users.slug' => 8,
'users.email' => 8,
]
];
public function getRouteKeyName()
{
return 'slug';
}
public function states()
{
return $this->hasMany('App\State');
}
public function cities()
{
return $this->hasMany('App\City');
}
}
State.php
class State extends Model
{
protected $fillable = [
'name',
'slug',
'initials',
'manager_id'
];
public function getRouteKeyName()
{
return 'slug';
}
public function manager(){
return $this->belongsTo('App\User');
}
public function cities(){
return $this->hasMany('App\City');
}
}
City.php
class City extends Model
{
protected $fillable = [
'name',
'slug',
'state_id',
'manager_id',
];
public function getRouteKeyName()
{
return 'slug';
}
public function manager(){
return $this->belongsTo('App\User');
}
public function state(){
return $this->belongsTo('App\State');
}
}
