From the SmackDown Women's Roster:

#14. Charlotte Flair - With Becky Lynch winning the triple threat number one contender match for Asuka's title on SmackDown, Charlotte is the clear favorite to win the Royal Rumble Match. There is absolutely no doubt she will be in the match and might just win it all.
#13. Carmella - After winning the Mixed Match Challenge with R-Truth, Carmella won the right to enter the Royal Rumble match at #30.

#12. Mandy Rose - Rose announced her participation in the match on WWE's Twitter Page.
#11. Sonya Deville - Deville announced her participation in the match on WWE's Twitter Page.
#10. Naomi - Naomi announced her participation in the match on the January 8th episode of SmackDown Live.
#9. Zelina Vega - Vega announced her participation in the match via her Twitter.
#8. Billie Kay - WWE will need more women to fill up the spots and Billie Kay along with Peyton Royce can have some good story-telling moments in the match. It is almost certain she will make it to the Rumble match.
#7. Peyton Royce - As mentioned above, Royce will also certainly make it to the Rumble match alongside her tag team partner Billie Kay.
#6. Lana - Lana is one superstar I really doubt will make it to the Rumble. Recently she was put into the Rusev-Nakamura storyline and is currently injured in kayfabe. This just might put her out of the Rumble match just so they have space for one more surprise entrant. But given how popular she is, I'll still bet on her making it to the match.
#5. Becky Lynch - Becky Lynch is the current odds on favorite to win the Women's Royal Rumble match. If she does not win the SmackDown Women's Title against Asuka it is more than likely that she will make it to the Rumble match. Given the fact that the betting odds are rarely wrong, I'm sure Becky will make it to the Rumble match.
