I had someone access my phone remotely and remove photos from my phone and icloud. Can these be recovereda

He’s not remotely accessing your iPhone. However, because he knows your Apple ID and password he has access to your iCloud account. You have Messages and Photos syncing to iCloud and when you do any action you take from one device to iCloud it happens to everything.

Unfortunately if those deleted items are not in the recently deleted folder, you can’t get them back.

However, you can prevent him from doing this again by following If you think your Apple ID has been compromised - Apple Support

when you follow these steps, make sure you change your password. Then you are going to look at all devices connected to your Apple ID and remove any that are not yours. By removing devices like his Mac, he won’t have access to do this again.

Your device cannot be accessed remotely. Perhaps they know your Apple ID and password. You should change your password. If your items are not in Recently Deleted, they cannot be recovered.
