I saw people talking about the Chains age in Linked Universe, and I have my thoughts on them.
I've done a LOT of research on the Links and how old they were, I even tried to figure out how long Legend was in Koholint for. (We go with old Canon because new Canon doesn't make since,(Footnote 1) but basically that's the last time we see Legend in normal Zelda Canon)
Anyways-
This is from Jojo's QnA doc on the Linked Universe Discord- ^^^
And this is my thoughts on their ages.
Side note, I'm not going off of looking up their ages through google, I'm going off info you can find in game and cross referencing it with other games and the Hyrule Historia and Encyclopedia.
Time was 9 in his game and that's about 20 years later so he would be 29. (Unless if we counting Majora's Mask, then he could be 30-32)
Twilight was a "Late Teen" (Also it does state hold old he is) so 17 making him 21 to 22.
Warriors is also "Late Teen" (He was a trainee at the beginning of the war) making him 22 to 26
Sky is also stated to be around 17 making him 18 to 19
Wild is 117 and this would make him either almost 118 or just turned 118.
Legend just became "Of age" in ALBW and that's 16 in his era making 17.
Hyrule we know is 16 making him 18.
Four is 15 or 16 in Four Sword, but he isn't "Of age" so probably 15. making him 17.
And we know Wind is 13 almost 14. (He said it himself)
I just find it very funny the Toons are the youngests.
Age explanation and footnotes below cut.
Time - He is 9 at the beginning of his game and becomes an "Adult" 7 years later at 16. This is one of the times it proves that 16 is "Of age" in the Zelda series. We aren't sure how much time has passed between Oot and MM, so we can guess he's 29 to 32 (Making Link in MM 10 to 12 as a good guess.)
Twilight - It's stated in a guide that he is 17. His game also was originally supposed to be a continuation of Oot and MM in the Wind Waker style, with Time all grown up and living on his own. But they changed it to what it is now. So it's just 17+4 or 5 making him 21 to 22.
Warriors - There is no official age and you do NOT need to be 17 to wield the master sword. All we know is that he's "Late Teens" making him between 16 to 19. Making his age in LU between 22 to 26.
Sky - He is stated to be around 17. Making him 18 or 19 (Even if we say he's 16, then he would be 17 to 19.)
Wild - he is 117 years old. We know this. it's been "Less than a year" so he could be almost 118 or already be 118, he probably doesn't remember his Birthday, so there is no saying exactly. (His Zelda should know though. Maybe.)
Legend - SO. I feel like people are gonna fight me on this, but I got the math and hours of research to back it. At the beginning of ALTTP, some guards say that Link shouldn't be out here or that he's too young to wield a sword (Or even start learning to) In BOTW Wild got the Master Sword at 12-13. And people said he was still very young and a prodigy, which means he was already learning the sword by that time. and we also know that in BOTW they think of "Of Age" as 17 instead of 16, meaning they probably make them learn stuff when they are a little older. There's also the connection to Oot, In Wind Waker its stated that Wind is the same age as Time when he Defeated Ganon (Making Wind Canonically 16) And Twilight is the age of what Time should have been when he decided to settle down, making him 17, which leaves us with Legend's age. Most likely taking Times age from the beginning of his game. LONG STORY SHORT- In ALTTP Link is between 9 to 10. NOW. The Oracle games, Link is still a CHILD, so before "Of Age" (Aka less than 16) A LOT of people call him a CHILD and wonder why he has a sword! making him most likely around 11 or 12. Same things with Link's Awakening. (FOOTNOTE 1). Then we have ALBW. Link has a job now and is learning to become a smith. so most likely after his return home, as well as he needs to learn this stuff before becoming a full adult, but then again he lives alone, so we could accurately say 15 to 16. SO LONGER STORY SHORT. We can say 16 and be GENEROUS. Making Legend 17 in LU (but probably closer to 16).
Hyrule - It's literally a plot in his game he is 16, making him 18 in LU.
Four - He is a Child in Minish Cap (So less than 16) and same with Four Swords. He has to be older than 12 because he was given a sword willingly. So between 13 to 15, but we can be nice and say 15 in Four Swords, making him 17 in LU.
Wind -
I do want to say, it's literally stated in his game he is the same age as Time when he KILLED Ganon as an ADULT. It's just the art style of the game.... He JUST turned 16, so people are still calling him a child. (Like how people call 18 year olds children in rl)
But also he does look 12 in game... ART STYLE WHYYYYYY
(also thats what Twi was supposed to look like lmaoooo)

FOOTNOTE 1 - The Encylapedia has wrong information that's easy to disprove and I want to throw it out a window. It also switched the order of the Oracle games and Link's Awakening, even though Oracle of Ages LITERALLY ENDS With Link taking the boat out to sea to head home, and LITERALLY Transitions to Link's Awakenings Opening. ITS THE SAME BOAT. I'm Gonna Cry- NINTENDO WHYYYYY.
