How to rearrange the location of the cities with their pictures on my iPhone 6s?

If you are talking about the Memories in the Photos app - these are done by DATE and location. Once you take the photos OFF your phone, you can edit and rename them any way you wish - and thus re-sort them. At that point, try loading the onto your phone (or into a Cloud, to save space on our phone) and then you can access them when and where you want. Frankly, unless you Really want to do this, and are GOOD at things like this, it is more trouble than it might be worth to YOU. I came home with over 600 shots from 5 countries - and some people want to scroll quickly thru all of the - and some people only want to see a certain date OR a certain location. So - for the time being, I have left things semi-edited on my phone. For people that come to my HOUSE to see them - I downloaded them, DELETED a couple of hundred boring or duplicate shots, and tightened up a shorter Slide Show. Put it on a thumb drive. Loaded it into Google Drive, too - and send the access code to anyone who wants to see the shorter slide show and NOT come to my house. OR - you can use Google PHOTOS - not the same things at All as putting them into Google Drive. PHOTOS (Google) defaults to "most recent first" - and who wants to see a cruise BACKWARDS?

So only you can decide HOW MANY photos you are going to do this to, and how much effort you want to put in learning a NEW way to do it, that fools you phone into accepting these as IMPORTED photos, after you clean out your PhotoStream. (or iCloud backup. If you also use THAT. Tried - took it off, since I share an account with my husband - and it just got to be TOO much - and throttled our phone storage)
