I don’t fully understand what you’re trying to do (your original question was about a RG, but your screenshots are showing a text element).
In any case, my guess is that you’re trying to display the most recent 3 respondents in a RG, in which case you just need to set you RG content type to RSPV, the data source to a search for RSPVs, sorted by created date: descending Yes, items until 3.
Then add a text element to display the current cell’s RSPV’s guest name.
Although, from your post, I’m not 100% sure that is what you’re trying to do?…
