Answer 1

I've done this by creating below post controller for the custom form to send data with attachment in Magento 2.

<?php
namespace Vendor\Module\Controller\Index;
use Magento\Framework\App\Filesystem\DirectoryList;
use Magento\Backend\App\Action;
use Magento\Framework\Filesystem;
class Post extends \Magento\Framework\App\Action\Action {
 const XML_PATH_EMAIL_RECIPIENT = 'section/email/recipient_email';
 const XML_PATH_EMAIL_SENDER = 'section/email/sender_email_identity';
 const XML_PATH_EMAIL_TEMPLATE = 'section/email/email_template';
 /**
 * @var \Magento\Framework\Mail\Template\TransportBuilder
 */
 protected $_transportBuilder;
 /**
 * @var \Magento\Framework\Translate\Inline\StateInterface
 */
 protected $inlineTranslation;
 /**
 * @var \Magento\Framework\App\Config\ScopeConfigInterface
 */
 protected $scopeConfig;
 /**
 * @var \Magento\Store\Model\StoreManagerInterface
 */
 protected $storeManager;
 /**
 * @var \Magento\Framework\Escaper
 */
 protected $_escaper;
 /**
 * @var \Magento\Framework\File\UploaderFactory
 */
 protected $uploaderFactory;
 /**
 * @param \Magento\Framework\App\Action\Context $context
 * @param \Magento\Framework\Mail\Template\TransportBuilder $transportBuilder
 * @param \Magento\Framework\Translate\Inline\StateInterface $inlineTranslation

 * @param \Magento\MediaStorage\Model\File\UploaderFactory $uploaderFactory
 */
 public function __construct(
 Filesystem $filesystem,
 \Magento\Framework\App\Action\Context $context,
 \Magento\Framework\Mail\Template\TransportBuilder $transportBuilder,
 \Magento\Framework\Translate\Inline\StateInterface $inlineTranslation,
 \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
 \Magento\Store\Model\StoreManagerInterface $storeManager,
 \Magento\Framework\Escaper $escaper,
 \Magento\MediaStorage\Model\File\UploaderFactory $uploaderFactory
 ) {
 parent::__construct($context);
 $this->_mediaDirectory = $filesystem->getDirectoryWrite(DirectoryList::MEDIA);
 $this->_transportBuilder = $transportBuilder;
 $this->inlineTranslation = $inlineTranslation;

 }

 $photos = array();
 foreach ($_FILES['photo']['name'] as $key => $image) {
 if (empty($image)) {
 continue;
 }
 $fileName = '';
 if (isset($_FILES['photo']['name'][$key]) && $_FILES['photo']['name'][$key] != '') {
 try {
 $target = $this->_mediaDirectory->getAbsolutePath('rga');
 $fileName = $_FILES['photo']['name'][$key];
 $fileExt = strtolower(substr(strrchr($fileName, "."), 1));
 $fileNamewoe = rtrim($fileName, $fileExt);
 $fileName = preg_replace('/[^A-Za-z0-9\-]/', '', $fileNamewoe) . time() . $key . '.' . $fileExt;
 if (!in_array($fileExt, array('jpg', 'jpeg', 'png', 'gif'))) {
 $this->messageManager->addError(__('Only jpg, jpeg, png and gif file types are allowed.'));
 session_write_close();

 }
 }
 if ($error) {
 $this->messageManager->addError(__('Unable to submit your request. Please, try again later'));
 session_write_close();
 throw new \Exception();
 }
 $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
 $transport = $this->_transportBuilder
 ->setTemplateIdentifier($this->scopeConfig->getValue(self::XML_PATH_EMAIL_TEMPLATE, $storeScope)) // this code we have mentioned in the email_templates.xml
 ->setTemplateOptions(
 [
 'area' => \Magento\Framework\App\Area::AREA_FRONTEND, // this is using frontend area to get the template file
 'store' => $this->storeManager->getStore()->getId(),
 ]
 )
 ->setTemplateVars(['data' => $postObject])
 ->setFrom($this->scopeConfig->getValue(self::XML_PATH_EMAIL_SENDER, $storeScope))
 ->setReplyTo($post['EmailAddress'])
 ->addTo($this->scopeConfig->getValue(self::XML_PATH_EMAIL_RECIPIENT, $storeScope));
 /* add photos to attachment; */
 foreach($photos as $pic) {
 $attachmentFilePath = $this->_mediaDirectory->getAbsolutePath('rga').'/'. $pic;
 if(file_exists($attachmentFilePath)){
 $transport->addAttachment(file_get_contents($attachmentFilePath,$pic));
 }
 }
 $transport = $transport->getTransport(); 
 $transport->sendMessage(); 
 $this->inlineTranslation->resume();
 $this->messageManager->addSuccess(
 __('Your inquiry was submitted and will be responded to as soon as possible. Thank you for contacting us.')
 );
 $this->_redirect('*/*/');
 return;
 } catch (\Exception $e) {
 $this->inlineTranslation->resume();
 $this->messageManager->addError(
 __('Unable to submit your request. Please, try again later.')
 );
 $this->_redirect('*/*/');
 return;
 }
 }
}
