Do insects breath out in the same place they breath in? Threw the spiracles.

Yes, the air goes in and out the same holes, the holes connect to a network of air passages inside the insects body. Some insects are passive breathers others actively pump air in and out of their bodies through the spiracles.

Then, what is the oxygen carrier? I think it's not made of iron. Is it's capacity big like hemoglobin?

I have heard about a cockroach that the holes for breathing in are different from those that are used fro breathing out. You might also be right because there might be other species of insects having same holes for both inspiration and expiration but, not all because I am pretty much sure about the case of cockroach.
