Hi Lucky,

Check KiCAD software.

I start peeking the file content, and discover its a
Personal CAD Schematic file.
Is there any free viewers for those file?

Schematic FILE

It has a header like this
Or is it interchangable, the file was created in 1994.

sch usually is generated by SCHematic capture CAD software. The others are probably other files generated by the same software.

Often if you view the contents of these files using Notepad or similar, somewhere in that mess of weird characters/ numbers you will also find the name of the CAD package as clear as day in readable form. Try it out. If you've already found it to be Personal CAD, then there you are !!

About a free viewer - I don't know. Google is your friend.

BOM might stand for bill of materials.

RPT might stand for report.
