Help identifying these wood species please

I bought a large lot at auction of Jatoba and Zebra wood. Before I milled the raw planks I had some questions on about 10% of the lot which I didn’t think were either. Now that I’ve jointed and planed, I’m still unsure of the species…

Sample 1 is obviously zebrawood and 2 is Jatoba… Anyone able to help out with 3 and 4?

I have some sapelle that looks like #4…I got it here:
