Hello. Pretty set. The white beads appear to be agate. The brown beads appear to be bronzite. The red beads have a few possibilities: lightly rub a soft cloth with a tiny dab of nail polish remover to test for dyes as I suspect they are dyed agate/chalcedony. I hope this helps.
I agree that the white beads are agate, but the red ones are sponge coral or possibly red jasper. The striations in the red beads are indicative of coral, from what I can see. Coral is often color enhanced, too.
@roses22 where did they come from, and are the findings sterling?
Look up red dyed agate & chalcedony. Then compare your beads with sponge coral and last, red jasper. I'm sure you will be able to identify them having it in hand and reference photos to check against.
definitely agree that they could be red jasper. the only reason I did not suggest coral is b/c I did not see the characteristic spicules - but that could easily be b/c of the angle of the photos.
