Is it Carnelion or Amber and is it an agate?

Solid quartz center. White agate lined. A honey carnelian color. Hard to tell which is the candidate.

This piece is agate with a quartz center. the coloration of the agate suggests carnelian.

Does it react with pool acid?

I would say definitely carnelian which is basically agate that forms in the proximity of iron or other minerals that give it the amber to red coloring. Looks like it might have nice banding if sliced or tumbled.

“You preachers of equality, the tyrannomania of impotence clamors thus out of you for equality: your most secret ambitions to be tyrants thus shroud themselves in words of virtue. Aggrieved conceit, repressed envy—perhaps the conceit and envy of your fathers—erupt from you as a flame and as the frenzy of revenge.”
—Friedrich Nietzsche

I have not scratched it but I will try it. Although it has been a bucket of rocks and has not scratched off.

The white caliche is very typical of weathered agate. That plus the banding makes this is high probability of being agate. It could be nice cleaned up, sliced, polished or just left as-is.
