I've marked File:My_Brother-2006.jpg as PD-self, but since you weren't the photographer for the others, I need confirmation that you've got permission from the photographers to release the images into the public domain.  Under current copyright law, everything is copyrighted as soon as it's created.  I think automatic copyright is the second-biggest mistake in copyright law (the biggest being the insanely long copyright terms), but it's the way things work.
