ULA has the 5H25 engine and hydrogen pump on display at their Space Symposium booth:

All that hard work developing the engine and piston pump and they end up a permanent part of a ULA static display?!??  That can't be a good thing for the Lynx program..  :(
Easy on the doom and gloom ;). The 5H25 was a development engine that we tested in 2015, and while the technology is similar, it isn't part of the Lynx program. This engine and pump were built for ULA as a subscale demonstrator for the 8H21. Also, as I understand it, the hardware isn't a permanent display and we sent it to them just for the conference.
I tried it at home

The Lynx didn't use Hydrogen - it had Kerosene and LOX pumps IIRC.

EDIT:
You know what, that was bad form.   The Lynx DOESN'T use Hydrogen.

How's it going with 8H21, are you making good progress?. Any ETA of test firing?

We are making progress, but I can't give out any specific details or dates.

Why 5H and 8H?

XCOR uses a number/letter/number format for engine designations. The first number is the thrust class of the engine, the letter is the propellant combination (LOX/hydrogen in this case), and the second number is the design number.
