Triplet (or more) paradox vs Twin paradox

Let there is a triplet of A, B, and C on an asteroid initially. A stays on an asteroid while B and C set out for a long space journey with high speed (say 0.5c and 0.9c) at the same time in the same direction relative to A. Assume each 10 years old at the time of departure. B and C are gone for 60 years relative to A. Afterward, B and C return home at the same time and reunited with A on an asteroid.

What would be the age of A relative to B and C?
What would be the age of B relative to C and A?
What would be the age of C relative to A and B?

Since each person can have only one physical appearance and one age. Thus who would be right?

Make it more simple: Let there are 96 clone brothers. Clone #96 stays on an asteroid while the rest take off at the same time with the following speeds relative to Clown#96, in the same direction for their long synchronized space journey. Assume each 10 years old at the time of departure. All 95 clones gone for 60 years relative to clone 96. Afterward, 1 to 95 return home at the same time and reunited with clone 96 on an asteroid.

Speed of clone #1 is 0.01c , #2 is 0.02c, #3 is 0.03c, #4 is 0.04 c, ..., #10 is 0.1c, ......, #20 is 0.2c, ......, #90 is 0.9c, ....,#95 is 0.95c

Each clone can have only one age and one physical appearance therefore who would be right on the age as well as the physical appearance of #96 clone?

What would be the age of B relative to C and A?
What would be the age of C relative to A and B?

I mean roughly how old look like w.r.t physical appearance - No need to calculate exact age - Sorry it was not clear

But since it is and, as far as we know now, can be nothing but a "thought experiment" who knows?

Since each person can have only one physical appearance and one age. Thus who would be right?

We are not going to do your homework for you!

The "fast speed travelers" had to accelerate. While they accelerate they feel a force. This is how me know who is stationary and who is a "fast speed traveler".

Indeed it doesn’t matter how quickly the person accelerates. One a change in velocity occurs you know who is moving relative to the other.

Standing on a sidewalk @ 1g is different than accelerating @ 1g?

They can pass by the stationary observer after getting their respective velocity - is it too difficult to imagine in thought experiment

Both B and C can use a separate rail car for their journey on a very big asteroid. A stays at home while B and C set out with high speed (say 0.5c and 0.9c) in their respective rail cars at the same time in the same direction relative to A. They attain their respective speed right after their departure. Assume each 10 years old at the time of departure. After 3o years relative to A, both B and C turn around and gain their respective speed in the same manner after taking a very short stop/ break (say 1 hr).  Afterwards, B and C return home at the same time and reunited with A.

Since A has only one physical appearance, therefore, physical appearance of A  will be same for both B and C – IMPOV

Wasn't the airplane (in which an atomic clock was sent for time dilation purpose) in acceleration mode when flying parallel to the curvature of the earth?

A would look oldest, b would look a little younger and c would look a lot younger

Does it address to what I said 

Since A has only one physical appearance, therefore, physical appearance of A  will be same for both B and C – IMPOV - so what is your opinion?.  Similarly,

Are you suggesting that people flying in air planes on Earth at ~0,0000003c get younger doing so ... regardless of the direction?

No, if "A" looks the same for both "B" and "C" then it dismisses time dilation

Why don't you reply to my question?

Person A, B and C are three distinct people, they don't have the same physical appearance nor will they age the same

Person A would age 60 years and look 60 years older, person B would age ~50ish years and look 50ish years older, person C would age ~25 years and look 25 years older

Would "A" aged 60 years and look 60 years older relative to himself and "B" and "C" as well?
