In order to start an index at zero, I found N. Abbasi is quite convenient. For instance,
(Note that in the original code by Abbasi, one of under scores _ in Notation[] was missing.)
However, with this method, we need to define these notations for each symbol.
I'd like to use any symbols with subscripts, like "a" in the above pic. with the same definition.
Any help is appreciated! Thanks in advance.

There's no need to use the Notation package to achieve the same behavior. For example:
SetAttributes[Subscript, HoldFirst];
Subscript[a_, i_Integer?NonNegative] := a[[i+1]]
Then:
a = {"Alice", "Bob"};
Subscript[a, 0]
Subscript[a, 1]
"Alice"
"Bob"
