What is this stone I keep seeing? Agate?

[Tetsuoh]

In my search to catalog types of ancient arrowheads I keep seeing these stone heads made out of some beautiful rocks.

And even if I have no experience in napping and have yet to try it - I keep seeing one stone in particular that gives me the drive to be able to use points I made out of it.

The lovely looking turquoise hued stone with reds and browns - is that an agate or a jasper?
Also, what is that light teal stone in the top middle of the second image?

I'm sorry if this question is somewhat silly to those on these forums, I'm still learning my stones  .

EDIT:
From Bone's topic I believe this is coral? I thought in a video I watched on youtube for stones one that locked very similar was referred to as an agate.

I think most of those arrowheads (mass made) are jasper. You said "ancient," so be aware these are all quite recently made - at least the ones you show here. I have seen them for sale many places and have often thought of re-knapping them - the bigger ones anyway, but you would have to find one in a flea market for cheap for it to be worth it. The smaller ones can however be quite cheap. Some may be agate, but I think most are jasper. I have seen some made of bloodstone and other very desirable and beautiful rock, but mostly agates.

Ah let me clarify - I was searching the net for pictures of ancient arrowhead designs and these kept popping up.

I of course knew they were recent as that is rather evident, but they did draw my attention.

And thank you very much for helping. I figured they would be a jasper or agate as most of the colorful knapping work I have seen was of them, but was unsure and wanted to get a better identification for later.

A lot of those are India agate.
