            $this->_tokenModelFactory   = $tokenModelFactory;
            $this->customerFactory      = $customerFactory;

    public function update($shop_name,$mobile,$email=null,$address,$customerId){

            $customer->getResource()->load($customer, $customerId);

            if($email){
               $customer->setEmail($email);  
            }

            $customer->setFirstname($name_Array[0]);
            $customer->setMobile($mobile);
            $customer->setLastname($name_Array[1]);            
            $customer->getResource()->save($customer);
            if($address){
                $data = ['block'=>$address['block']];
                $addressModel = $this->addressDataFactory->create();
                $addressModel->setFirstname($address['firstname'])
                    ->setLastname($address['lastname'])
                    ->setCountryId($address['country_id'])
                    ->setRegionId($address['region_id'])
                    #->setRegion($address[''])

                    $this->addressRepository->save($addressModel);
            }
            $message = [

            echo json_encode($message);
            exit;
        }catch(\Exeption $e){
             throw new InputException(
                __($e->getMessage())
            );
        }
    }
}

Setup script:

$customerSetup -> addAttribute('customer_address',
            'latitude',
            [
            'label' => 'Latitude',
            'system' => 0,
            'user_defined' => true,
            'position' => 100,
            'sort_order' =>100,
            'visible' =>  false,
            'required'      =>  false,
            'default_value' => '',
            'note' => '',


                        'type' => 'varchar',
                        'input' => 'text',

            ]
            );

        $customerSetup -> getEavConfig() -> getAttribute('customer_address', 'latitude')->setData('is_user_defined',1)->setData('default_value','')-> setData('used_in_forms', ['adminhtml_customer_address', 'customer_register_address', 'customer_address_edit'])-> save();

please try this out to your setup script.

public function install(
    ModuleDataSetupInterface $setup,
    ModuleContextInterface $context
) {
    $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
    $customerAddressEntity = $customerSetup->getEavConfig()->getEntityType('customer_address');
    $attributeSetId = $customerAddressEntity->getDefaultAttributeSetId();

    /** @var $attributeSet AttributeSet */
    $attributeSet = $this->attributeSetFactory->create();
    $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);

    $customerSetup->addAttribute('customer_address', 'latitude', [
        'label' => 'Latitude',
        'input' => 'text',
        'type' => 'varchar',
        'required' => false,
        'position' => 333,
        'visible' => true,
        'system' => false,
        'is_used_in_grid' => false,
        'is_visible_in_grid' => false,
        'is_filterable_in_grid' => false,
        'is_searchable_in_grid' => false,
        'backend' => '',
        'comment' => 'latitude'
    ]);


    $attribute = $customerSetup->getEavConfig()->getAttribute('customer_address', 'latitude')
        ->addData([
            'attribute_set_id' => $attributeSetId,
            'attribute_group_id' => $attributeGroupId,
            'used_in_forms' => [
                'adminhtml_customer_address', 'customer_address_edit', 'customer_register_address','customer_address'
            ]
        ]);
    $attribute->save();
}

hope this will work for you!.
