The first 2 pics are both:
Aphonopelma seemani - Costa Rican Zebra Tarantulas
and the third pic is:
Ephebopus murinus.
At least that is my opinion after having looked at my T's, and these pics. The first pic does however seem to be very black for a zebra. It was just a friendly debate I was having with someone selling a Aphonopelma seemani as a Ephebopus murinus - luckely I was planning on rehousing both of myne, so I dug them up

So, either he originaly got screwed when he bought them, or he got confused, which to a certain degree is understandable...
