Great photos! Not the greatest for identification purposes, but honestly, those would make great avatars or just plain tarantula pics, I love the angles and poses!
So, try grabbing a few photos from above so you can see the carapace a bit easier. Here is an example

The photos you added show the legs and colors great, but looking at the body would help a bit more. That second one is definately G. pulchra. I can't be certain without a better pic of the body, but I'll say G. pulchra. The first one looks like G. pulchripes, aka former G. aureostriata, but I've never had one and it doesn't look absolutely right, there's something wrong about it, so I'll wait until someone who is more experienced in this species comes along and corrects me. Last one is a spider
