Yes.  Just put each external on a different line.  So -

set the externals of this stack to "windows.dll" &cr& "mac.bundle"

Yes.  If they are all in the same folder you could do something like  
this (off the top of my head, not tested):

answer folder "Select folder with stacks
if it <> empty then
     put it into tFolder
     put defaultFolder into tOrigDefault
     set defaultFolder to tFolder
     put files() into tStacks

     repeat for each line tStack in tStacks
         if char 1 of tStack = "." then next repeat

         get tFolder &slash& tStack
         if there is a stack it then
             set the externals of stack it to "windows.dll" &cr&  
"mac.bundle"
         end if
     end repeat
end if

It is possible to set the externals for one stack and have it  
available to all stacks in the development environment.  I have  
created plugins that do this with other externals.

1) Create a new stack
2) Set externals property of stack
3) Put this in the stack script:

on preOpenStack
   start using stack (short name of me)

   pass preOpenStack
end preOpenStack

4) Put it in the Revolution/plugins folder
5) Go to Development->Plugins in the ide, select your stack.  Set it  
so that it opens when Revolution starts up and that it opens as  
"invisible".
6) Restart Rev and after launching you should be able to execute  
Valentina external handlers from the message box.
