Interesting names, though not really my style in terms of sound.
I don't see why they couldn't be used now. Rikissa could make a unique alternative to something like Rebecca or Melissa.
A few years ago, I saw a game show contestant, probably in her mid-to-late 20s, called Richeldis. I always thought that was an interesting name, and has a similar vibe to Rikissa/Richeza. Somehow it feels even more archaic.
