function _load_data()
owner = {0}
admin = {0}
vip = {0}
dude = {0}

local file = io.open("sys/lua/rp/1.txt")
local string1, string2, string3, string4 = file:read("","*n","*n","*n")
	owner = string1
	admin = string2
	vip = string3

file:read("","*n","*n","*n")

Why is the first one "" not "*n" ?

You should use
table.insert to add values to your tables. what you're doing is basically

a = {} (a table)
a = 11111 (a number)

No way would that work. Especially if you're looping it to gain all elements.

Console was written, ROFL.

Anyways, you probably want to use string.match function:

	vip = {}
	dude = {}

	local file = io.open("sys/lua/rp/1.txt", "r")
	local string1, string2, string3, string4 = string.match(file:read("*all"), "(.*), (.*), (.*), (.*)")

	table.insert(owner, string1)
	table.insert(admin, string2)
	table.insert(vip, string3)
	table.insert(dude, string4)
end

local file=io.open("1.txt","r")
local line1=file:read("*n")
local line2=file:read("*n")
file:read("*l")	-- for unknown reason you need to read till newline then discard it.
local line3={string.match(file:read("*l"),"(%d*),(%d*)")}
local line4=file:read("*n")
line3[1]=tonumber(line3[1])
line3[2]=tonumber(line3[2])

That's just an example how to read them.

Now line1,line2,line3,line4 contains these

line 1 equal to value at line 1, you can change the variable.
That's just an example, use it if you think that's suitable for you because we don't know what those numbers mean at your file. Maybe like money or something like that.

	local f=io.open("sys/lua/rp/1.txt")
	owner,admin=f:read("*n","*n")
	f:read("*l")
	local v=f:read("*l")
	for w in v:gmatch("%d+") do table.insert(vip,tonumber(w)) end
	dude=f:read("*n")

why not do this the easy way? Save your data as Lua and let Lua do the work for you.

Example Data in 1.txt:

return {0,0,{88222,117228},88305}

Load the data into a table:

1
2
3
4

local func,err = loadfile("1.txt")
if func then
	mydata = func()
end

now your data is all in a table and easy to use however you want to.

Strange, i never use ipairs. That should be problen in the another script.

EDIT: Oh, i understand now. You may want something like this

local function list_usgn_by_comma(_)
	local __={}
	for ___ in _:gmatch("%d+") do
		table.insert(__,tonumber(___))
	end
	return __
end

addhook("startround","load_data")
function load_data()
	local f=io.open("sys/lua/rp/1.txt","r")
	owner=list_usgn_by_comma(f:read("*l"))
	admin=list_usgn_by_comma(f:read("*l"))
	vip=list_usgn_by_comma(f:read("*l"))
	dude=list_usgn_by_comma(f:read("*l"))
	f:close()
end

Code above shouldn't throw any ipairs error in your script.

what line? it's bit hard to debug them if you don't give us the line number. Maybe the variable is overwritten somewhere in your another script. Check it again, or add this after the declaration of load_data

load_data()
