I'm not sure about that - have you tried it?

Again, I'm not sure about that. An ounce of experimentation here would
save a pound of guessing - just open up a few instances, windows
whatever and try it!

Here's some more guessing :-)

Another option would be to use the -n option in Kate and put every
document in a new instance. The kate man page is a bit contradictory on
the point, but it seems that default in kate is to add tabs and windows
to a running instance if one exists. That means that using xkill on any
kate window kills them all, because xkill kills at the instance level -
i.e., will kill the process that created the window you select. Since
kate by default uses the same instance to create new tabs and windows,
killing one kate tab or window will kill every kate tab and window. But
if you tell kate to set up a new instance for each document you open,
you should have the fine-grained control you seek.

Of course, if using tabs is something you cannot do without, you are
stuck.
