I love lua scripting and do you have a problem with that?

Dont upload it on file archive.
On question what you need to improve i tell you:
What's actually this lua planned to be? What do you want to see there yourself? What's your thoughts about to do with this lua after you done?

What kind of rating do you want? Performance, beauty?

In terms of performance, well you don't use anything "that" heavy besides several function calls and creations, and conditions, so nothing to worry about performance, except one global variable that's used for nothing other than holding character 169 (you could use 
\169
inside string dammit).

Contrawise for the beauty, you need to properly tab your scripts and add necessary whitespaces between words (not symbols). It would improve human reading for you, and for the coders who want to learn. Also remember that there's no convention you need to follow, like you need to use pascal case for global vars. Here's what I call a beauty.
function Person(name)
	local new = {}
	new.name = name
	
	return setmetatable(new, {
		__index = {
			call = function(self)
				print('Hey, ' .. self.name .. '!')
			end
		}
	})
end

local person = Person 'Orlando Hutapea'

person.call()


Also there's no rating scripts with scale like 0-10. Just saying.

Let´s pretend you have a lot of other items in the shop. And you want to change the price of 5 items or sth. You would have to change it in line 17 (menu) and in line 27 (where you loose it) for each weapon (lot of work and everyone makes mistakes)

You could zip your offers into a table:
1
2
3
4
5
myWeapons = { 
	["Laser"] = 16000,
	["Molotov"] = 1000,
	-- todo
}

And the rest is all code with no real values whatsoever.
It should look like this:
1
2
3
4
if (player(id,"money") >= myWeapons[v]) then
	parse("equip "..id.." "..myWeapons[k])
	parse("setmoney "..id.." "..player(id,"money") - myWeapons[v])
end

This makes the script way to complex and long.
But once its done its very easy to edit weapons with pricing and stuff

What's the matter on using 
string.char()
? I indeed understand he could've declared his variable as local and that he should move the variable inside 
sayShop2
function since he's using it for a specific block scope but whether you use \169 or string.char() you get the same final result.

     parse("setmoney "..id.." "..player(id,"money") - myWeapons[v])
end

I actualy need to know this because im actualy working in my custom player shop script

Its just a menu...
Still working in the buttons...

@user GeoB99: Yes, it would get the same result. But in terms of performance, there must be a difference between creating a variable and not creating a variable at all, right? Although it's unnoticable, it wouldn't be a good practice if you let yourself creating variables for unnecessary things (like for character 169 in this case) if there're other better ways. And... if you look closely, 
string.char(169)
would do more work: accessing table; calling function; and creating a literal. While if you do the 
\169
, it's already part of the string.

@user baRD: Here's an explanation for you, piece by piece how this code works:

• 1st line: It'll create a conditional IF statement which checks if the player's money is greater than or equal the amount required to purchase a certain item. If the condition is deemed as true then it'll pass to the conditional body code (the further lines below);

• 2nd line: The regular 
parse()
function to execute ordinary CS2D commands. What it does is to tell CS2D to equip you with the item you've purchased.

• 3rd line: Finally, it'll set the player's money based on purchase acquisition.

By the way, 
[k]
stands for key which in our case is the item string you see in the 
myWeapons
table while 
[v]
stands for value which is the actual money value. Keep in mind that tables in Lua are somewhat associative arrays. You should take a look at Lua pil or other tutorials to see how tables actually work.

@user Dousea: I see, you're right. But still, it will only apply to bigger scripts where performance is a critical step, for smaller scripts it doesn't really make sense.

Creating a variable for the color character would make sense only if it could change in the future (editing all occurrences in a big script isn't what one wants to do).

Moreover, name "c" isn't a good name for a variable. A global variable with such name (in terms of length) is a bad habbit. Short names are good for a local-scope variables (loop interating ones, like "i" in for-loops). And what is important, it says nothing about purpose of this variable. 
colorSign = string.char(169)
is more clear when you see it in the middle of someone's code.

The error means you miss an end. Every for, if, etc. needs an end.
EDIT: See line 62. You start with an "elseif" which is wrong, you always start with an if.
Solution: Delete the end on line 61
(EDIT2: My edit is complete bullshit. You TABed wrong and I didnt read carefully)

Answer to your question which user GeoB99 already answered:
Instead of equipping "laser" like you do, I equip whatever is in the table.
As I explained, I´d do this to easily edit the code later on.

Loops (for loops - you better read into it they help A LOT!!!) usually look like this:
1
2
3
4
5
6
for k,v in pairs(myWeapons) do
	-- now k and v are local variables
	-- k(ey) is like a counter, or in this case the name of the weapon
	-- v(alue) is the value inside, or in this case the price of the weapon (see my code above)
end
-- now, k and v do not exist anymore because they were local

Local variables only exist for the actual scope (or: they only exist until the 'end') like k and v above.

You are probably new to programming/lua so feel free to ignore my idea because you would have to rewrite almost everything.
Actually you asked where you can improve and I gave you an idea.

And btw, you can use elseif on line 25-51 to improve perfomance.

@user Avo: I must say that creating the variable is useless after all because what other character that could change the color of text?

@user Bowlinghead Using elseif doesn't improve performance. It just uses different logical condition.

EDIT:
Sorry, misclicked your username, user Mora.
