These are various Honda/Acura transmission gears and 3/4 syncro hub assembly. It is difficult to know exactly what these fit without detailed measurements and tooth count but from the photos they all look like parts for the B Series transmission or possibly the GSR transmission. I have supplied a few URL's with some good photos. Note: not everything in your photos goes to just one transmission. These parts are from two or three different model transmissions.

its a hodge podg of two different transmission, large gear ax15 1st I think, syncro ax15 3/4

Reason:
I cannot find any AX15 gears that look like these & have the same teeth/spline count
