Charles was king the moment his mother, Queen Elizabeth, died. Holding a coronation ceremony is customary and traditional, but it's not required. He's still the king whether formally crowned or not.
Camilla is queen solely because she's married to the king. If Charles dies, she does not become queen in her own right. William is the heir to the throne and will become king when Charles dies.
It's "crowned" - coronated is not a word
