Or John, or Shang, though I think he's younger than he seems. he just acts older.

Aladdin is definitely in his teens, Philip is only 2-5 years older than Aurora (so 21 at best), Ferdinand is canonically 18 (I read it in a book about Snow White's animation), and Adam is 21.

Naveen looks like somewhere in his 20s. could be early or late but I'd guess early. I highly doubt his parents would have wanted to coddle him that long. Same for the king not wanting to put off Charming's marriage too long.

he looks older than most of them

I'm pretty sure Flynn is suppose to be the oldest....could be wrong though.

John is 27
Flynn is 26
Shang is 23 or 24
Charming 21
Ferdinand 21
Adam 21
Phillip 20 or 21
Naveen 20
Eric just turned 18
Aladdin is 16 or 17

^Source?

Don't know how old John is, but he seems to be his early 20's. Maybe 23
Aladdin and Eric are 18
Naveen is 20 (confirmed by Disney)
Shang is probably 19-22 maximum
Prince : ?
Charming: 20-22
Phillip is 2-5 years older, so what AudreyFreak said
Beast turns 21 at the end of the movie

Flynn is confirmed by Disney to be 26 years old. He is portrayed as a wise man and experienced everything (even in the ads). I am positive that no prince is 27 and older.

I think this was my first countdown that I held on Fanpop

I read it all on the Disney website but John Smith in real life was 27 or older when he met Pocahontas so I just went with that.

I think John Smith is like 30. (because Pocahontas was about 22 in the movie) Call me whatever you want, but THAT'S how old I think he is. I also think Shang is 25. And I think Phillip is about 23. Aladdin may be 21-22 but I DO know Flynn is about 26 and Naveen is 20. No word on how old I think Ferdinand, Charming, and Eric are. Recently, I've been beginning to think Adam is older than 21.

Flynn, John or Adam.

Or Flynn or Shang.

And Prince.
