Prince Harry's official royal title is Duke of Sussex. He was granted this title by Queen Elizabeth II upon his marriage to Meghan Markle in May 2018. Although he retains this title, he and Meghan stepped back from their roles as senior members of the royal family in early 2020 and have since adopted a more independent lifestyle.
He will still be Prince William.
If the father (Prince) does not hold another title, his children will be Prince or Princess. The off spring of that Prince will also be a Prince, but not so with the Princess - especially if she marries.
Prince Harry is not a king. His title is Prince Henry of Wales.
Harry's wife will become a princess and will take the major title of her husband, depending on what that is at the time For example, when Kate married William, she became a princess, but took on the title of 'Duchess of Cambridge' because the title of 'Duke of Cambridge' out-ranks your bog standard prince title. When Charles and Diana married, Diana took the title of 'Princess of Wales' because Charles was the Prince of Wales, which was a much bigger deal than just your normal 'run of the mill' prince.

As a member of the royal family he inherited the title.
The same thing that happened to Elizabeth- she'll be in line to be Queen. She'll knock Harry from being 3rd in line to the throne. And then when she marries, her husband will take a title such as Duke of Edinburgh (a guy who marries into the family can't take a higher title than his wife, who is of royal blood. Therefore, he couldn't be King.).
If he dies without children, Kate will be the dowager (whatever her former title was). And then Harry and his line will succeed to the throne. However, if William dies before he marries Kate, then Kate gets no title at all.
