Yes you can, but it's usually best to #declare a texture and use it's name 
as a parameter:
#declare MyTexture = texture {pigment {rgb <1,1,0>}}
MyMacro(0,1,MyTexture,2,3)

You can nest unions within one another. Yes it's easiest to union the handle 
to the door before you move the back left or right edge of that union to the 
origin to rotate (open) it.

I would recommend having a 'HingeSide' setting of '1' for right, or '-1' for 
left. Then, for the door handle you can do something like
translate <-HingeSide*0.4*Width,HandleHeight,DoorThickness>
// Note the '-' sign to bring the handle to the opposite side to the hinge.

then with the union of the door and handle you'd have something like:
translate <HingeSide*Width,0,0>
rotate y*Door_OpenAngle
translate <-HingeSide*Width,0,0>
