Futari Wa/Max Heart:
It has been confirmed that Mipple used to be a comrade of Honoka's grandmother. However Mipple does not seem to be as old Honoka's grandmother which give us the idea that Mipple and to extent Mepple age slower. Porun and Lulun are quite obviously kids.
Splash Star:
We can infer that Flappy and Choppy age like Mepple and Mipple and that Moop and Foop are similar to Porun and Lulun.
Yes 5/GoGo:
Syrup and Milk are around the age of Nozomi,Rin,and Urara so we can put them out of the way. Coco and Natts are a bit harder to pin down but from their human designs we can infer they are around Komachi and Karen's ages and
1.Are only acting as adults to disguise themselves.
2.Are technically adults according to the rules of the Palmier Kingdom.
Like as I said before I doubt Precure would add pedophile characters.
Fresh:
Tarte seems to be older then the cures so I'll put him around 19. Chiffon is a baby obviously.
Heartcatch:
We saw Potpurri be born so she's an infant. Coupe is an older fairy. Cologne seemed to be mature like Moonlight akin to how she acts with her team. Chephre and Cofferet were at Moonlight's last battle however the could be fairly young due to the way they act.
Suite:Siren is 14 like the cures and while Hummy and Siren did I grow up together Hummy seems to be a kitten compared to her.
Smile:
When we look at Royale Candy we can see she's about 4-5. When Pop turns into a human he looks around the same age as the cures making him 13-15.
DokiDoki:
From what we saw in the human forms Cheryl and Raquel look around 10-12,Lance looks 4-5, and Davi looks like and adult. Ai is a baby.
Happiness Charge:
This by far was the season that gave us the least hints to the ages of the fairies. I honestly don't know because I could put them in any age group.
Go!Princess:
Pafu and Aroma give me Candy and Pop vibes so I'd put them at the same ages as Candy and Pop. Shamour is around 28 while Kuroro seems to be around...13.
Mahou Tsukai:
Mofurun can't physically age but mentally and according to Cure Mofurun's height she's around 13. Ha-Chan doesn't age consistently so...
KiraKira:
Pekorin seems around like 3 while Chorou is old lmao. Kirarin and Pikario are 13 like Ichika,Himari,and Aoi.
Hugtto:
Harry's around 16-18 and Hugtan...is like complicated. If you watched the show you'll know what I'm talking about.
Star Twinkle:
Fuwa seems around the Candy or Pekorin age group while Prunce seems he's around the age of the Cure's.
