How to run multiple loops at the same time?

for q=1,100 do
wait()
	print(q*2)
end

for i=1,200 do
wait()
	if not i%2 == 0 then
		print'not EVEN close' --I know, not very punny, oops, funny
end
end

What's going to happen is the first loop is going to run, and then once it's over, the next loop will run. The only way(in my mind) is to make a separate script for the second loop. But i need 6 loops to run at the same time, and I don't want 6 scripts appearing whenever the round restarts(i need 6 loops to run when the round restarts for various purposes). So how can i get 6 loops to run at the same time in the same script?

You can use spawn. This will cause the function you give it as an argument to run separate from the rest of the script (although it's actually much more complex than that, read the wiki about it if you want). This allows you to run two loops at the same time.

function loop()
	for i = 10,20 do
		wait(1)
		print(i)
	end
end
spawn(loop)

for i = 1,10 do
	wait(1)
	print(i)
end

You can also use coroutines to get a similar effect. The wiki has pretty much your exact example on it, so I won't bother writing one.

use coroutine, it lets you run more than 1 things on a script: http://wiki.roblox.com/index.php?title=Function_dump/Coroutine_manipulation

coroutine.resume(coroutine.create(function() --the script will be running both this and the other loop at the same time
	for q=1,100 do
		wait()
    	print(q*2)
	end
end))

for i=1,200 do
	wait()
    if not i%2 == 0 then
        print'not EVEN close' --I know, not very punny, oops, funny
	end
end

and you could do:

coroutine.resume(coroutine.create(function() 
	for q=1,100 do
		wait()
    	print(q*2)
	end
end))

coroutine.resume(coroutine.create(function() --now both loops are in a coroutine, so if you added anything else it would run both loops and whatever other code you put
	for i=1,200 do
		wait()
	    if not i%2 == 0 then
	        print'not EVEN close' --I know, not very punny, oops, funny
		end
	end
end))

And if you need to script to run more than 3 things at once you can just add more coroutines!

Recursive solution to making a loop and printing it 100 times

function PrintvalTimes(value)
if(value == 0) then --base case
print(value);
else
	PrintvalTimes(value-1)
end


end
PrintvalTimes(100)

then if you wanted another loop, just use this function as a model
