atemi kata part deux

thanks adi for clarifying the atemi kata

here are some questions:

BASIC ATEMI KATA
Hachi dachi; what is this exactly? do toes point at 45 degrees or straight? break right to kiba dachi; starting with right hand, five vertical punches.

Right foot steps forward, pivot left to zenkutsu dachi, middle block with left hand; i assume this is like gedan barai, not a chudan uchi uke - you block down or block middle?right
lunge punch to the chest ; right foot back, pivot to kiba dachi, right low block ( eyes left )
