Just wondering…
Hmmm, well I don’t think I’ve read anything about their ages, but I can make an estimated guess.
Linguini could be anywhere from eighteen to twenty-one. I can’t see him being any younger or older than that.
Colette is probably a little older; maybe twenty-three or so…
Remy acts like an older teen, in my opinion (“But dad, I wanna make things!!!”). Eighteen or nineteen, possibly.
Emile, being Remy’s older brother, is probably the same age as Linguini, if not a little younger.
Django is probably in his mid-forties.
Skinner is probably the same as Django, but maybe a little younger.
These are all my opinions, but they sound pretty reasonable, don’t you say?
The strange thing is, obviously, as Remy and his family and friends are rats, their actual life span is pretty short. I don’t know what happens at the end of the movie, but whatever it is, if it’s the sort of situation that leaves an ending that can continue, such as, I dunno, Remy [spoil]getting in control of the restaurant-[/spoil] as with that kind of thing, obviously it leaves an idea as to what Remy would be doing in the future. His lifespan causes problems, since he’ll age really quickly in comparison to humans.
I’d rather pretend he lives to be in his ninties. 
Maybe talking rats live longer…?
Good question, pixarkid!
I was thinking the same question myself only a couple of days ago; these are my predictions:
Remy - Anywhere from 17-19 years of age; probably eighteen.
Emile - 16 years of age (give or take).
Django - Mid-forties (mid-40s).
Linguini - 18-21 years of age.
Colette - 20-30 years of age; probably late twenties (late 20s).
Skinner - 35-42 years of age.
Anton Ego - 60+ years of age.
The sad fact is that, as lizardgirl pointed out, a rats’ lifespan can stretch anywhere from 2-4 years, depending on the rat and his/her life style, eating habits, and living conditions. A very nervous and skittish rat may only live 1 1/2 years – in this, I am using one of my previous rats, Hannah, as an example. Just the opposite may occur, as well. I’ve heard of rats exceeding their average lifespan by two, three, or even four years. One particular rat – who went by the name of Noah, I believe – lived to be seven years of age, an outstanding number.
Taking these facts into consideration, we can safely announce that Django is probably nearing the end of his life – he’s probably got another good, solid year to live and that’s it. Remy is probably a tad luckier; he may exceed his average lifespan by a few more months to a year or two, due to the fact that his eating habits are exceptionally healthy and hygenic. Poor, gluttenous Emile, on the other hand, probably won’t live past two years if he keeps up his eating habits…
So yeah. There ya’ have it. Rather sad, when you think about. Unless Pixar’s rodentia live forever, Remy and his whiskered companions won’t be around for much longer. Hopefully, that’s not the case, but you never know. I’d like to think that they survive only as long as our love for the characters is/lasts. Henceforth, and if all goes well, Remy will live forever.

Actually, Remy is the elder sibling in his family. Contrary to the fact that Emile constantly calls Remy his “little brother”, Remy is the oldest. Emile only calls his brother “little” because of his apparent size (Remy is smaller and skinnier than Emile).
Trust me. I obtained this information from a reliable, internet source (or, several websites…to be exact).
Mitch - I’d realllllly like to know where you got said info on Remy being older than Emile…
I can help you there.
There’s a kid’s book based on the film called “Oh, Brother!”, told from Emile’s point of view. Emile acknowledges the fact the Remy is little, but older. The Myspace page also supports this.
In regards to Remy being older than Emile…
There’s always a bit of shakyness with a first born. As this person/rat will be the one to carry on the family if no one else…well…“comes out”. This would explain why he’s a bit pressuring to have Remy be well…more rat-like.
Now for age…hard to say really.
Unlike the common rat, Remy’s diet is more than trash-chugging. Contrary to it, he, if I recall, never had it…with the acception of possibly growing up.
But anyway. Given fine food and Remy’s talent to coordinate it into being delicious, and possibly healthy, his life-span, as well as his pack’s, would extend past normal rats.
I agree with Remy being in his rat-teens as the story itself unfolds it as in a way of “self discovery”, “self-esteem”, and the inevitable search for a reason of living.
As for Emile…I’d guess being about…well not CLOSE to Remy’s age given his personality and humbleness…if Remy would be 16…Emile could be around…12 or 13. Django himself is probably in his mid-30’s early 40’s. But that’s in human terms, I’m shaky with it.
In terms of how long they’ll live, probably more than a common rat thank’s to Remy getting himself and his pack/family out of the trash-diet. However…given Remy’s “Contribution”…he’ll probably live longer than anyone close to his age in his pack.
Dash - Read Ryan’s post. (Thanks, Ryan!)
I never thought of that. Good point…
Just…gotta open your mind for anything and everything
Ohhh, so Remy is older than Emile! Well, that’s cool! 
Seems you forgot you knew heh. Your signature shows that Remy…is a bit more mature than Emile ^_-
Nexas - Heheh. Agreed.
JesusFreak - Cha – he’s the big brother, like me (the only diference being that I’m not a boy; however, I am the oldest sibling in my family)!
It’s my job to entertain heh.
Then again…maturity doesn’t neccesarily come with age eyes drift in Ran’s direction…
I thought that Remy was younger because Emile called him his “little brother”? amiright? Emile said it right before Remy went to get the key for the fridge.
Most likely due to Remy’s size. Have a sister who’s older than me myself, though I’m twice as tall.
Yeah, I know plenty of adults that still act very immature (And not in a fun, playful way…)
Probably due to the Human element.
imayweepepenly - Welcome to Pixar Planet, dude!
Nexas is right, it’s do to his size… 
It makes sense that Emile is younger than Remy, because as his older brother stated, [spoil]“He’s easily impressed”[/spoil]. Older siblings are often looked upon with amazement for their skills.
