Can someone give me some ideas for characters in my story?

I need some characters to be in my King's Court… like some Dukes, Lords, or any other people and i was wondering if you had any ideas… I would like names and personality if you can give them… I already have some characters…

King Michale Mathias Gregory Walker (King Walker VII)- The King can sometimes be cruel at times and has a short fuse. When he is denied something or is betrayed he gets very upset. He also struggles to gain complete control of his country (Belzonia). He has browned tanned skin with a low cut goatee. He has a full head of thick hair that is cut. His eyes are chocolate brown.

Queen Casandra II- The Queen is a beautiful woman. Her eyes are dark-honey brown. Her hair is medium length and is dark-brown. Her skin is soft and is the color of brown sugar. The Queen is healthy but can sometimes be swayed by her emotions.

Head Minister Croft Charleston- Head Minister takes his job very seriously following things to the T. However, he always finds himself going head-to-head with the king because of their disagreements of how to run things. Croft's job is to advise the king and take care of certain things like taxes, church, and making sure the country is to prosper.
