If you need to control the largset number of open files in Win9x, the best approach is to create an entry in the CONFIG.SYS with a FILES= entry in it. Under NT, you can associate a custom CONFIG.SYS with an application, but that is not an option with Win9x.

The details of many memory and screen-related items are controlled through a .PIF file that may be associated with a given .BAT or DOS executable; if no .PIF exists for a specific entry, the inherited values from _DEFAULT.PIF are used when the file starts under Win9x. Under Win9x, the FILES behavior is established well before the PIF might be able to step in to make any adjustments - this is different under NT.

>Q3. What is the bast value for FILES & BUFFERS

There's no fixed answer, since it depends largely on individual machine configuration. Both have consequences for free conventional memory in a DOS VDM, and needlessly making any adjustment to buffers is perhaps the most common really clear sign that a total incompetent has worked on the PC, since after boot happens, the BUFFERS setting has no measurable effect on DOS VDM performance, but can do things to needlessly occupy space in the HMA or conventional memory space that could be put to better use. FILES obviously affects the number of files that could be opened by a VDM, and each entry eats some space from memory otherwise available to applications.

The solution long-term is to get away from the DOS and Win16 environment, so that these issues are dompletely non-existent.
