"Weight Loss As the Paleo diet is by nature pretty low-carbohydrate": Paleo is not necessarily low-carb. You could eat squash, root vegetables, and fruit all day for nearly all your calories. I actually don't doubt that you can lose weight on the paleo diet, though. You can lose weight on almost any vaguely healthy diet.
"Cancer Patterns in Inuits" : Cancer has many other causes than diet, and this study in no way isolates diet as the factor in disease-patterns in Inuits.
"This William Lands paper": This solely studies omega-3/6 intake and health. Not the overall health effects of the paleo diet.
"Good Calories, Bad Calories" does have an explanation of why the medical establishment has made its recommendations. Still, it is written by one non-expert. Hardly enough to make radical lifestyle changes for.
"Dr Barry Groves" OK, this looks possibly legit.
I'm not going to try to figure out the rest, given the poor quality of the preceding.
