Hey~ (Ahh, I love Haru from Free! and I'm kinda excited to see you cosplaying him haha)
Sooo, I think that the head piece is three pieces according to the last reference. Like turban, head cover, and then scarf. And I think it's all separate because the last reference also shows all three separate and how to tie the scarf. (But I'm sure you can just combine the head piece and turban because it's mainly together) I'm not sure how to fold/create the turban/shawl, but I think you can fake it through draping and forcing it to look like it haha.
I found some tutorials for the pants:
I think the top under his shawl is like a sports bra/binder-looking piece, so I think it's pretty easy to make.
I found a cool tutorial on fakin' some hot abs:
I have no idea on making prop swords other than paper mache-ing cardboard and painting it... Here's some more tutorials then:
And the gold cuffs on his shoulder can be make with paper mache. Just crunch up some paper to look like a sausage, glue some elastic to each end to make it stay up on your arm, paper mache it, and paint it gold. I think the same should go for the belt, unless you want to get fancy and use Worbla (but I don't recommend it).
Oh my gosh that was a long post... XD Hope I helped and good luck!!!!
