King, Queen and Kaido don't have reported height numbers.
However, Big Mom is 28.5 feet tall, so a little taller than Jack. Kaido and BM are of similar height, so it's best to assume Kaido is around 30 feet at most. King and Queen stood next to Jack chapters ago and they all were the same height.
Basically all 5 characters are about 30 feet.
Black Maria is taller than all of them definitely, but she is NOT Numbers height. Giants are 70+ feet. Numbers are taller than this. At most she is Giants height on the short side.
