Request for multiple photos and how to send to DropBox

Hello,
I built a brief post event survey to go to registrants for a travel trip. I would like to have them upload one or more photos from their trip, and then have the photos sent to a trip specific Dropbox folder. In addition, I would like the photo file names appended with the name of the trip (instead of IMG_1183.jpg or iOS_Photo1.heic). So, I have a few asks:
Is it possible to upload more than one photo?
Is it possible to have a workflow where the photos are sent to a Dropbox folder?
Can I have the photos appended with the name of the trip (taken from an embedded data field).
Any help would be very appreciated!
Thank you
