Why are the shadows in some of the pictures going in different directions when NASA claims that there was no exterior source of light, except the sun ?
In photographs, they're (usually) pretty poor 2d representations of 3d objects. Any sort of HORIZONTAL LINE HERE is guess work and usually a terrible guess at the light source

Again, the answer has a fundamental correctness to it. However, most of the Apollo photos are actually excellent 2D representations of exactly what one would see, if one payed attention, on any photo taken in similar lighting conditions on Earth (Waspie has clearly shown this to be true on several occassions).
There are no anomalies present in the Apollo lunar surface photos.
A discussion of this could get into some detail (and has), and would require specific examples in order to explain in more depth.
But, you can reproduce the absolutely natural shadow effects seen in all Apollo photos, including the shadow bend where ground slopes up and down or undulates, and the common representation of parallel shadows seeming to converge when photographed through the 2D dimension of a photographic lens portraying 3D objects on a flat surface, almost anywhere on Earth.
These shadow arguments are a shallow HB attempt to cast doubt upon Apollo, based on the same thing that every HB idea about the program is based upon: lack of understanding of the sciences and technologies involved in space flight, and the nature of the space environment.

Why was the surface of the moon described as being like powder/dust... yet a rocket landed on the moon and the pictures show ZERO dirt/dust on the landers footpads ?
Any blast from the lander's rocket would throw the dust down and to the side,very little would land on the feet. There is no air disturbance for the dust to billow around in. Throw the dust to the side and it will go that way, it won't come back to land on the feet.

Again fundamentally correct in the answer, and is associated with the last issue raised:

And no dust cloud either, specially with how the moon is supposed to be covered by powder fine dust ?
I covered this in the question about the take off. Also, dust falls much faster in less atmosphere. The ONLY reason dust floats on Earth is due to the atmosphere.

Although this answer is incorrect in part of its terse expression and thus can be confusing.
Lets talk about "dust clouds".
Dust clouds are caused on Earth. They are the result of microfine particles of dust interacting with air. The particles are so small and light that they are suspended and move in reaction to contact with the air. Some particles fall, and others are suspended and swirl around in the moving air, which moves as a result of the impulse of whatever caused the dust to fly in the first place, or by the fact that the air is moving already.
On the Moon, we have no atmosphere. So, there's nothing to suspend dust particles. The move in linear fashion from the point where the LM DPS engines exhaust gasses make contact with it, outward and upward at an anglke, all moving away from the LM as it settles. There are no clouds formed, because there is no air to form them. The dust moves in sheets radially outward and upward (not down) in all directions from the source of impulse.
What happens when the engine cuts off (when the LM is between 3 and 8 feet above the surface) is that the impusle imparted to the dust ceases, and the dust stops being moved off of the ground. The effect is akin to that which you'd see if you take a garden hose, and spray it outward from you in a stream, then, cut it off suddenly. You see the end of the water stream move away from you, arcing balistically outward and falling to the ground, following all the rest of the water stream.
This is precisely what the LM crews saw when they cut down their descent engine with the dust blowing off of the lunar surface. The end of the dust sheets streaked away from them, falling in a ballistic arc some distance away.
Since there's no air to create clouds of dust, the end of the dust streams move away and fall to the surface some distance away. Nothing is suspended in the air...since there is none, and nothing falls on the LM or on its footpads.
Bottom line: there are no such things as dust clouds on the Moon. There cannot be any. It's physically impossible.
The LM footpads had no dust on them, and there was no cloud created by the engines because they cannot exist there. It's actually basic physics.

Why are there no stars visible in the pictures, the sky is supposed to be super clear if you are on the moon.
Can you see stars during the day on Earth? It's the same damned thing on the moon. The sun bleaches out any chance of seeing stars.

In a fundamental way, this answer is true. In another, it leaves far too much unexplained.
The reason you cannot see stars on the surface of the Moon in photographs, or with the naked eye (in most all circumstances) is indeed because one was always in broad daylight on the lunar surface...a much brighter and broader daylight than is experienced on Earth. The eye, and the camere lens, have an aperture ( or , an iris, as the case may be) which closes to allow the eye (or the camera) to see or image brightly lit objects, and thus does not allow one to perceive very dim (relatively speaking) objects such as stars.
It is true that you cannot see stars during the daylight on Earth. Even if we had no atmosphere (which is a rather ridiuculous idea, since we wouldn't exist if there wasn't one), we couldn't pick up stars when the sun was in the sky. The sky would be black, certainly, but until the sun stopped making our eyes close up, we wouldn't be able to pick up the relatively dim stars. This is a natural effect, both biologically concerning the human eye, and photographically concerning the camera---which was set to photograph brightly lit surface objects.
The camera could not image stars at those settings and in that light condition.
In fact, stars weren't all too visible during most periods of manned space missions, on the Moon or not. This is because the Sun was generally casting an extremely bright light on the scenes. One could do it, on a night side orbital pass, with the cabin lights off to allow the eye to adapt to darkness...but for the most part, the Sun was always out, prohibiting the view of massive star fields.
