You can't stack this way, but you can simulate stacking. 

If you define 

clonevar total = VAR2 
replace total = VAR1 + VAR2 

you can then superimpose the bars for -VAR1- on top of those for -total-. 

twoway (bar total period, yaxis(2)) (bar VAR1 period, yaxis(2)) 
(scatter VAR3 period) (scatter VAR4 period), by(VAR5 VAR6)

Warning: not tested. 

Defining -total- as VAR2 in the first instance with -clonevar- ensures that it inherits any variable label for VAR2, which can help in graph legends. 

Alternative: Look at -rbar-.

How can I stack the bars (VAR1 and VAR2) in the following command?

. twoway (bar VAR1 period, yaxis(2)) (bar VAR2 period, yaxis(2)) 
(scatter VAR3 period) (scatter VAR4 period), by(VAR5 VAR6)
