Body position, also known as stance, basically helps you to gain maximum strength and/or defense for a certain attack when attacking, or to be able to absorb an attack much more effectively when defending.
There are a vast amount of stances, but we are only going to talk about the 5 Basic no Kamae: Chudan, Jodan, Hasso, Gedan and Waki.
It will be a long read, but worth it.
Chudan
Your body:
Your right foot most be in slightly front of your left foot. Your left foot will work as your base support, as you will be standing with the front area of it. Your legs must be parallel to your shoulders, this means your right knee most be in the same Y-axis as your right shoulder, and your left shoulder in the same Y-axis as your right shoulder.
Your back most be straight, though because of your footage, you may seem to be a little inclined forward.
Sword position:
Your sword most be in front of you. With your right hand, you will hold the sword close to the tsuba (hand guard), the hand back of your hand facing outward. Your left hand will be close to end of the tsuka (the handle), the back of the hand facing downward.
Your sword most be inclined above the X-axis from your waist. The tip of the sword will be pointing the eyes, throat or mouth of the opponent. When confronting an opponent with a steel sword the effect is that of an invisible weapon, since the opponent cannot see any part of the blade except for the very tip.
This is how it should look:

Jodan:
Your body:
Your body settings are very similar to Chudan no Kamae. Your left foot most be in front of your right foot, wide. You will incline your right foot a little, ready to make a step, your weight will be in your rear foot. Your knees and shoulders need to be parallel with each other. Your back most be straight, as it will contain your explosive power to swing downwards.
Your sword position:
Your sword most be above your head. With your right hand, you will hold the sword close to the tsuba, the back of your hand facing upward. Your left hand will be close to end of the tsuka, the back of the hand facing outward.
The sword most be between 3-5 inches apart from your head. If seen from the end of the handle, your sword most be 135 degrees from the X-axis is creating (45 degrees backwards).
Jodan kamae is the most fearsome of kamae. It is both an open invitation for the opponent to foolishly try to strike at the abdomen, yet a deadly trap because the person in jodan kamae can easliy strike and cut men or kote. When a steel sword is used the effect is that of an invisible weapon since only the cutting edge is seen by the opponent. This will cause great fear in the opponent, and doubt of the distance from the where you are.
Here is an image (the second image is a slight variation of Jodan, but still falls into Jodan no Kamae):

Hasso
Your body:
Your back must be straight, showing no weakness to your opponent. Left foot slightly in front of the right foot; left knee bend forward, right knee “locked” straight. Shoulders and feet must be parallel. Your body will seem to be rotated toward your right (the chest and overall body), though your left foot and head direction will be facing the opponent.
Your sword position:
The hands are positioned near the face, with tsuba of the sword near and level with the mouth. The sword will be pointing upwards, 90 degree if possible. Right hand close to the guard, left hand close at the end of the handle.
Hasso kamae is not comonly used in kendo matches, it is deceptively open to attack. The opponent is likely see this kamae as an invitation to attack which is just what a person in hasso kamae wants, who instantly strikes men or kote.

Gedan
Your body:
The position is exactly the same as Chudan.
Your right foot most be in slightly front of your left foot. Your left foot will work as your base support, as you will be standing with the front area of it. Your legs must be parallel to your shoulders, this means your right knee most be in the same Y-axis as your right shoulder, and your left shoulder in the same Y-axis as your right shoulder.
Your back most be straight, the leverage of the sword will help you maintain it.
Sword position:
Right hand close to the tsuba, left hand directly behind it. Your sword most be pointing at "the opponent's knees". Your arms stretched, though having your elbows bent a little in order to manuever easier. The sword will be inclined in a lower Axis than your waist.

Waki No Kamae
Your body:
The position is almost the same as Chudan, though with some modifications.
Your right foot most be in behind your left foot, leaving a gap between both legs of approximately the distance between one shoulder from the other. Your right foot will be facing the direction of your body, that is, outside; your left foot will be facing toward your opponent.
Your back most be straight, the leverage of the sword will help you maintain it.
Sword position:
Right hand close to the tsuba, left hand directly behind it. Your sword most be pointing at the opposite direction you are facing, with the sharp side away from your body. Your arms shouldn't be so stretched, as you would use a whip-kind motion to slash and gain momentum. The sword will be inclined in a lower Axis than your waist.
Waki kamae is not used in kendo matches, the kamae places the sword to rear opposite from the opponent effectively hiding the sword. Hiding the sword makes it difficult for the opponent to judge the distance for a strike. Appearing defenseless, or inviting the opponent to make a careless attack creates doubt and even fear in the opponent.
