Maybe this is a solution for you (or at least a point to start):

	#!/bin/sh
	xterm -geometry <blahblah> -title "App 1" -e su root -c "app1" &
	xterm -geometry <blahblah> -title "App 2" -e su root -c "app2" &
	xterm -geometry <blahblah> -title "App 3" -e su root -c "app3" &
	xterm -geometry <blahblah> -title "App 4" -e su root -c "app4" &	

The -geometry is set as ROWSxCOLS+X+Y, e. g. 80x25+0+0 for
the upper left corner. See "man xterm" for further options as
you could need them.

You could create a "wrapper script" that calls four scripts which
only start one of the four applications each.

~/bin/run_1:
	#!/bin/sh
	xterm -geometry <blahblah> -title "App 1" -e su root -c "app1" &

~/bin/run_2:
	#!/bin/sh
	xterm -geometry <blahblah> -title "App 2" -e su root -c "app2" &

~/bin/run_3:
	#!/bin/sh
	xterm -geometry <blahblah> -title "App 3" -e su root -c "app3" &

~/bin/run_4:
	#!/bin/sh
	xterm -geometry <blahblah> -title "App 4" -e su root -c "app4" &

~/bin/run_all:
	#!/bin/sh
	~/bin/run_1
	~/bin/run_2
	~/bin/run_3
	~/bin/run_4

Not very elegant and tidy, but should work. You could add some
checking to the first script mentioned so it gets a clue which
application is *not* running and restart it when called, not
starting those that are running again (second session).
