I want to get the second character from comment-start.

Would one use (aref kmnt 1) ?

 (let* ( (kmnt (string-trim comment-start))   
         (lngt (length kmnt)
         (ankr (if (= lngt 2) 
                   (aref kmnt 1)
                 kmnt)) )

Any reason not to do (aref ... 1)? Not sure what you're worried 
about.

What is the standard way of capturing characters from strings, is it with aref ?

I don't know what makes something "standard" for you. As covered 
in (info "(elisp) String Basics") a string is an array, and as 
covered in (info "(elisp) Array Functions"), aref can be used to 
fetch an element of an array.

And as a random sample of some core code, aref is used 17 times in 
files.el from what I can see.

Cheers,

        - Joel
