Trouble with vecs and variables (making clones)

Questions
1

I have a simple code here that stops when the square collides with another square. If I wanted to make lots more squares of random sizes (clones of the original square) come through , like an “avoid the square” game , how could I do that without duplicating several lines of code? So each level spawns increasing amounts of squares to try and dodge.

 displayMode(FULLSCREEN)

 function setup()

 print("w"..WIDTH.." h"..HEIGHT.."")
 level=1
 distance=0

w=50
w1=math.random(10,200)
x1=WIDTH+w1
y1=math.random(0,HEIGHT)    
speed=3
hit="not hit"

t=ElapsedTime
tt=ElapsedTime
end

-- This function gets called once every frame
function draw()
-- This sets a dark background color 
rectMode(CENTER)
background(40, 40, 50)

-- This sets the line thickness
strokeWidth(5)

-- Do your drawing here
rect(300,CurrentTouch.y,w)

--1
rect(x1,y1,w1)

text("w "..w.."",500,600)
text(hit,400,600)
text(distance,100,600)
-- line(300+w/2,0,300+w/2,HEIGHT)
-- line(x1-w1/2,0,x1-w1/2,HEIGHT)

if ElapsedTime-t>0.01 and hit=="not hit" then
w=w-0.0025

x1 = x1 - speed

    t=ElapsedTime
end

if ElapsedTime-tt>(speed)^-1 and hit=="not hit"then

distance=distance+1

    tt=ElapsedTime
end

if x1<300+(w/2)+(w1/2) and x1>300-(w/2)-(w1/2) and y1<CurrentTouch.y+(w1/2) and             y1>CurrentTouch.y-(w/2)-(w1/2) then

hit="hit"
end


if x1<0-w1 then

    w1=math.random(10,200)
    x1 = WIDTH+w1
    y1=math.random(0,HEIGHT)
    speed = speed + 1

end  ,
end

@ewan You use tables to hold as many squares as you want to create.
