None of those seem to have anything to do with PRISM. This is a confusing situation, because two secret surveillance programs were leaked on subsequent days. These seem to be related to the first leaked program, which involves collection of Verizon's call metadata. That seems pretty clear-cut. Verizon has issued a non-denial, it's in line with what we've known about the NSA's conduct since 9/11, and various members of congress and the executive branch have commented on it.
PRISM is a completely separate issue and one I'm much more skeptical about. I also haven't seen anybody specifically admit to PRISM's existence, so I'd be interested if you can find a better source.
