How do we read the Hive Blockchain Witness table?: A list of question seeking answers

Being a newcomer to Hive, I am still trying to understand how the Hive Blockchain consensus mechanism works. Unfortunately, the information out there isn't the most friendly to gather.

To begin my journey, I shall try to understand what this table below is about.

I hope fellow Hivers who knows the answers to my questions below can offer a comment or two to help.

  1. What is so special about being in the top 20 on this table?
  2. What is Votes(MV)?
  3. What is the APR?
  4. Why is there a price feed?
  5. What is the AC fee?

I appreciate any help!
