Two basic questions about iPhone usage

Hi everyone! I just updated to the latest iOS. I now have two questions that I don't know how to work with, and I'm sure you can help me!
1. I've mistakenly hidden some purchased apps on the App Store on my phone. How do I get them back? Note, my phone is an iPhone SE, and if a PC is needed to sort this out, mine is running iTunes on Windows 10.
2. Can anyone tell me how to rearrange the VoiceOver rotor? I didn't backup my phone so I set it up as a new phone, and now the rotor options are all over the place. Can you teach me how to custom all the items on there? Hint, since I work a lot between English and Chinese, I'd love to have the "Language" and "Characters" options in the most convenient place of operation.
Thanks for your help!
