Because their parents did not want them to have titles
In most places, a prince is best addressed as 'Your Highness.' There may be more region specific titles as well.
Windsor is their surname. Their titles will be Prince and Princess of Wales.
Assuming you mean one of the living British princes called Edward, there are two: *HRH The Earl of Wessex (The Prince Edward, son of The Queen, Elizabeth II) has two young children: **Lady Louise Windsor **Viscount Severn (James), who is expected to inherit his father's peerage titles *HRH The Duke of Kent (Prince Edward, The Queen's cousin) has three adult children: **The Earl of St Andrews (George), who is expected to inherit his father's peerage titles, and is married with three children **Lady Helen Taylor, who is married with four **Lord Nicholas Windsor, who is married with one son
Prince Andrew's children, Princess Beatrice and Princess Eugenie, do not typically use their royal titles as they have chosen to lead more private lives away from royal duties. Following Prince Andrew's stepping back from royal responsibilities amid controversies, the decision was also influenced by a desire for them to have more independence and to pursue their own careers. The royal family has historically allowed some flexibility in title usage to reflect personal choices and public perception.
What are Prince Charles's royal titles

The proper title for an emperor's son is "crown prince" or "prince imperial," while the daughter is typically referred to as a "princess royal" or "princess imperial."

None. It was the Five Nations tournament when Gareth Edwards was playing - Italy has not joined during that time.

They all have titles now. Princess Anne is the Princess Royal. Prince Andrew is the Duke of York. And Prince Edward is the Duke of Wessex. This likely would not change because Charles would be succeeded by his son William as heir to the British throne.
I am answering this presuming that you are referring to the current Prince Phillip of England, husband of Queen Elizabeth II. Prince Phillip is by birth a Prince in Greece and Denmark, but when he married Elizabeth he renounced those titles. He does not hold a specific princedom in the UK today (i.e. Prince of...), but is referred to as Prince because he is the Prince-Consort of the Queen. (To be honest, his actual title and right to the title Prince is debated). With regards to actual titles he holds, his most significant (highest in precedence) is Duke of Edinburgh.
