Hi there I am level 14 at league. I am not a very good player atm. The only 2 champions i mostly use are Xin Zhao and Varus. I don't mind how much it cost but maybe something easy i can play with. Thank you for trying to help
Garen is a really easy to play tank. All you have to do is max e and you win lane. Annie is an easy mage to play. Warwick is an easy jungler and one of the only junglers that can do well there without runes because of his sustain, he also has one of the best ccs in the game: suppression. Some easy supports you can try are sona, annie, or soraka. And the easiest adcs to play are Caitlyn and ashe.
Good luck
Another fairly easy jungler who is easy to play but not as crappy as Warwick is Udyr. Udyr has no skill shots and is very versatile. I learned to jungle on him. Skarner is another easy one to pick up. Nunu is one who can last a decent amount without runes. His consume is like a 2nd smite. Also ends up being better than Warwick. Warwick after you get past level 20 falls off hard as his lack of crowd control becomes more apparent. Ashe ADC is strong right now. Jinx is also a favorite among beginner players. Caitlyn as recommended before is another good choice. Sona is easy to learn as a support. Blitzcrank support is straight forward and is a terror to any new players who have never met him before. Morgana supporting can be fun and simple. And Lulu support while expensive isn't too difficult to pull off. As far as mid laners go since you like Varus the champion Xerath may be to your liking. Lots of skill shots but unlike Varus Xerath has stuns and slows on his abilities. Twisted Fate is another champion who you can practice skill shotting with. Lux is still my mid laner of choice. Vladimir is a mage/tank who runs on hp rather than mana (So his abiltiies cost some of your health) and scales very well into late game. Top laners: Garen is easy. If you learn Garen you might as well learn Darius as he is the Noxian version of Garen. Top lane Pantheon can be fun. I haven't mentioned Mundo yet but he is a smart choice for top lane. Mundo's ultimate is a "Do not die" button. He's a great tank. My two favorite top laners though are Shen and Renekton. Shen is a defensive pick and Renekton is an offensive pick.
Champions who you shouldn't buy starting out: Alistar, Evelynn, Shaco, Lee Sin, Orianna, Syndra, Taric, Zilean, Poppy, Viktor,
All you need m'boy, is The Interior Crocodile, Renekton. 
Wait. How did you post here? I wasn't allowed until level 30....
Anyway, just a silver 5 but whatever. Here I go.
The term "Unique" in an item means, can't be replicated. You can't buy multiple of. Well, you can, but the Unique passive would be useless except on the first item. Second, "Unique Passive" with a name(EX: Enhanced Movement) cannot be replicated even on a different item. THIS MEANS DON'T BUY MULTIPLE BOOTS. LIKE, EVER. YOU WON'T RUN LIKE SANIC.
AP and AD are Ability Power and Attack Damage. AD is fairly simple. It increases your basic attack's damage, as well as some types of ability's damage. Ability Power is ability specific, but more common.
Cooldown reduction only goes to 40%. After that, all cooldown reduction is void and you might as well not have it.
Runes and masteries are VERY important. They seem like a little thing, but they can save your life, get you a kill, help you win lane and game in general. Its very important.
There is a key meta to the game. As in, people do this, so do it.
Top lane goes fighters and tanks usually. People who can take a hit but deal damage as well, and still sustain. Usually melee, but you might encounter the mysterious creature named Teemo who will render your autoattacks null and void... try to bait out the blind on him then go in. If you can't win well, just sit under tower and don't feed.
Jungle is a mix of characters. Anywhere from a tank, to a fighter, to an assassin. Usually you don't use ranged or common supports though(except maybe Taric). At the beginning, all characters except Shaco(who you will later learn why, but don't play him early in your League experience) need what is called a 'Leash'. Its someone that sits by you while the monsters in the jungle spawn, and help you take that first jungle. They back off though so they don't steal it(usually). You most always want to start on the Kruggs(rock monsters) or Gromp(big toad/frog thing), smite it as soon as your ready to take it down, and then start going at it. Your leash should back off after several hits and allow you to take it.
Mid-lane are usually mages or assassins. Mages build tons of AP and basically just farm for the most part of the early game, until mid-late game when they commonly excel and help team fights a ton. Assassins variate between AD and AP and are basically... well, assassins. They assassinate. Burst down squishies(non-tanks or fighters, sometimes even fighters) and get kills for their team.
Bot lane are ADC's and tanks or supports. Marksmen are champs who build AD. They fight from a distance to stay safe and are commonly squishy. Some ADC's build a bit of AP, such as Corki or Kog'Maw. Supports tend to... well... support. They buff their ADC's with extra stats, heal them, tank for them, set up kills, etc.
Play easy champs to learn lanes. As recommendations for some to learn, start Udyr jungle, Corki ADC, Soraka(just spam heal and poke really) or Blitz support, top lane Malphite or Jax, and do Nidalee or Cho'Gath for mid lane.
Kinda low on time atm so y'know, but there's some basic tips. Good luck, have fun!
Generally the easier to play champions are the cheaper ones since the older champions didn't have as many hard to manage mechanics like the new ones. Some of the easy to play champs in my mind are as follows
Top- Garen Mid- Annie Jungle- Warwick/Udyr Support- Annie, Soraka ADC- Any adc with an escape, Corki, graves etc
Awesome thanks for the help :D
