In case you can't read the labels of characters, top to bottom and left to right:
Blazor Wulf
Lazor Wulf
Stupid Horse
Cannon Wulf

Height headcanons:
Blazor is the shortest of the 4 at 5'4"-5'5"
Lazor Wulf is the shortest guy at 5'7"-6'
Cannon Wulf is the second shortest of the 4 at 6'1"-6'3"
Stupid Horse is the tallest of the 4 at 6'4"-6'6" (lanky boy-)
