Essentially, you want to have a script that is constantly making the sprite fall (changing its y by a negative amount), except at the times when it's touching something solid. Simple example:

forever if (not <touching [ground]>) {
    change y by (-1)
}

How so? Might need to use a variable or two to get it to only activate the gravity when not doing those things:

When Space key pressed {
    set $jumping to (1)
    broadcast Jump and wait
    set $jumping to (0)
}

forever if (not <touching [ground]>) AND ($jumping = 0) {
    change y by (-1)
}

Or something like that.

are they all the same colour? if so, simply have something looking like this
forever{
if (touching colour (select colour)){
grav = 0
} else {
change grav by -1
}
if(Key up Arrow is pressed){
if(grav = 0){
grav = 5
}
}
change y by grav
}

Here, download this http://scratch.mit.edu/projects/shadowwarrior77/417818 and take a look at its scripting, then just use it...its pretty simple and its great!

Also, you can change how high and how fast he falls by changing the Yvelocity

It should work, just make sure to put a black outline on everything you want the sprite to walk on or land on

you need to have a sprite, a color, or maybe a function that can be sensed so that you can sense whether or not you are touching a "floor".  If what you really want is true GRAVITY you need some advanced physics, which would mean you need velocity. you can have a yvel variable and change y by yvel. I'm not sure how you are sensing whether you are touching a box... I wouldn't know the best way to do t so that it worked with your current scripts. I would need an example of it.
