Southern English accent (dunno if you were only looking for American accents?)... I don't personally pronounce the wh- and w- prefix any differently in any of those words. But some people might. Also don't know if you were looking for this, but some of those word pairs are pronounced differently, e.g. wheel/will, whurry/worry, when/win. An interesting one to think about maybe is one and won. Some people pronounce "one" beginning with a /hw/ sound, and won sounds similar but with only the /w/ sound.
