In the thread title you talk about syntax errors and those are checked with the -n flag.
Your examples 1) and 2) are semantic errors but syntactically correct.
1) copying a file called FILE1 is syntactially valid, no matter wheter you have defined a variable with the same name or not.
2) what do you mean when you say "a file which is declared"? Anyway, a file can be created any time. It is no syntax error just because a file referenced any way is not there at the time you check the syntax.
3) may be a special case of 2). The comment may be interpreted as an executeable with arguments (which does not have to exist at the time you check).
