Usually, Top's something like a Tank/split pusher, Mid will usually be a dmg carry that has the potential to burst people off, jungler will either be tank/dmg but the focus will be if he/she can pull off ganks and support lanes at the right place and time while SPs control the game, depending on how he/she wards/dewards/roams, they can dictate the pace of the game. Lastly, ADC, you will need to some time to farm up abit but it's always fun to fight 2v2s btm as long as you're not the one losing out too much haha.
You can buy the cheapest champs and focus on one or two. You'll need to discover the limits of your champ, like how you should engage, what's a safe distance and etc, at the same time since you'll be up against different champs, you'll slowly learn what you need to avoid when fighting those champs.
A simple Mid/Top which you can start with, would be Annie. Q refunds mana and helps you last hit and she has a decent burst, pretty straight forward, just flash in and cast all your skills then hope that your opponent dies. (there's more to it but u'll discover it) Or for me, I started out with Morgana. You just shield yourself and run away whenever someone tries to gank you, I max W and time it so that I hit at least 5 creeps at one go, so it's just farm and farm and farm till I see a chance to kill (or take tower), but the problem comes when my opponent knows how to counter me (which is to push my lane faster than I can push his).
For ADC, I think I started out straight with Lucian and Caitlyn. Lucian has less range but a potential for high burst, he's a really good champ for catching opponents off guard and killing them while Caitlyn has a long reach to poke and stay safe, a decent waveclear but the problem comes when your opponents can dive straight into you, the clever use of her traps will help you to survive longer and you can do a lot with the reach especially once you have items.
