"...am assuming (for now) Roster Resources is accurate in identifying player who'll be Rule 5 eligible for the first time."
No more assumptions with regards to RR. The error on Arauz I noted previously should have been an immediate red flag to check their work on other players and particularly the international signees. Updating from the work I did for the 2018 Rule 5 draft thread, the following 4 categories have to be considered when evaluating potential 2019 protectees:
Category
1. A HS draftee taken in 2015 or earlier: none
2. A college draftee taken in 2016 or earlier: Bailey, Dawson, Adcock, Toro, Wrenn, Nick Hernandez, Hartman, Donato, Benedetti, Ryne Birk, LaRue, De Goti, Colin McKee, Jones, Robinson, Manea <1>
3. IFAs aged 16-18 at signing who inked a contract in Aug 2015 or earlier: Urdaneta, Yeuris Ramirez, E. Valdez, Humberto Castellanos, L. Rodriguez, Paredes, Rosado, Felipe Tejada <2>
4. IFAs aged 19 and older at signing who inked a contract in Aug 2016 or earlier: Anibal Sierra, Yohan Ramirez, Jose Bravo, Ronel Blanco, Carlos Sierra, Alfredo Angarita <3> <4>
<1>Problem #1 to fix is that Nick Hernandez, Ryne Birk and Colin McKee need to be added since RR failed to include them.
<2>Problem #2 to fix is that Yeuris Ramirez, Humberto Castellanos and Felipe Tejada need to be added since RR also failed to include them.
<3>Problem #3 to fix is that Anibal Sierra, Yohan Ramirez, Jose Bravo, Carlos Sierra and Alfredo Angarita need to be added since again RR failed to include them.
<4>Problem #4 to fix is certainly the biggest name of all and involves the incorrect inclusion rather than incorrect exclusion. That would be Yordan Alvarez. Alvarez was signed by the Dodgers on June 15, 2016. That was a mere 12 days away from his birthday. A birthday on which he would have turned 19. So he instead falls into Category 3 (age 16-18 at signing) which means he still has one more year before becoming subject to the Rule 5.
So the corrected list with the 60 players who have an R5 bullseye on them...

Remind me to shoot myself if I ever cite RR again. MLBTR owns and/or is affiliated with RR but the accuracy of one certainly doesn't extend to the other.
