If I understand you correctly, something like
this is closer to what you need. I have used
locals throughout, partly a matter of taste.

local X "x1 x2 x3 x4 x5 x6 x7"
local Y "y1 y2 y3 y4 y5 y6 y7 y8 y9"
local Z "z1 z2 z3"
local yis "a b c d e f g h i g k"
local v "replace"

foreach y in `yis' {
		reg `y' `X'
		outreg2 using res100407, `v' br e(all) seeout
		local v "append" 	
		reg `y' `X'
		outreg2 using res100407, `v' br e(all) seeout
		reg `y' `X' `Y' `Z'
		outreg2 using res100407, `v' br e(all) seeout
}

There may be a cuter way to do it, but sometimes what looks
like rather repetitive code is just easier to understand,
to maintain and to modify.

With the code below, I would have regressions run one by one like: reg
a x1 and then reg a x2  until reg a z3 and then reg b x1 and so on.

But what I would like is for it to run :

reg a $x, reg a $x $y, reg a $x $y  $z and then the same for b etc...
Could anyone help on how to program it please.

global x  "x1 x2 x3 x4 x5 x6 x7"
global y  "y1 y2 y3 y4 y5 y6 y7 y8 y9"
global z "z1 z2 z3"

local yis "a b c d e f g h i g k  "
local xis "$x $y $z"

foreach y in `xis'{
foreach x in `yis'{

local v= "replace"
local n=1
	reg `x'  `y'

local v="append"
local n=`n'+1
outreg2 using res100407, `v' br e(all) seeout
}
}
