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).

NAME
svc, ci, co, svclog - shell version control system SYNOPSIS
ci [-lu] file co [-l] [-r rev] file svclog file OPTIONS
-l For ci, checkin, checkout again, and lock file -l For co, checkout file and then lock the archive -u After checking in, do not delete the file -r Check out revision rev instead most recent revision EXAMPLES
ci -u file # Check in file co -l file # Check out file and lock archive co -r 2 file # Check out version 2 DESCRIPTION
Svc is the Shell Version Control system, patterned on RCS. It maintains a sequence of versions in archive files, so that new versions can be checked in (added to the archive), and old versions can be checked out (made available). To create an archive for file, check it in with the -u flag. This action will prompt for a log message and then create an archive called file,S in the current directory, or in the subdirectory SVC if it exists. The file will not be deleted, but will be made unwritable. To update the file, check it out with the -l flag. Then modify it, and check it back in, giving a new message when prompted. After this process has been repeated many times, the archive will contain the entire history. Any version can be checked out using the -r flag. To get a printout of the history, use svclog. SVC(1)
