Hey, Silver player here to give my terrible advice.
Is not a really great top laner. He's got some decent, if not bleh waveclear but sustain wise will lose to most of the champions you picked. He's not a carry at all, he's a disrupter and you want him to stay in the jungle. His CC is insane and can keep an entire team down easily. He's got everything you'd want in a tank, just he lacks significant damage.
If you like keep the enemy team pinned then he's a go to, but you have to rely on your team to do damage as he cannot 1v1 most anyone unless they're low health or already potentially dead. He's just not able to carry sadly, but I wouldn't toss him aside since he's good for a team that needs peel.

is great top lane, and his sustain damage is exceptional especially once you start getting his cores. His struggles are trading against champs that poke often, but excels in champs that like to go in early aggression because of his spammable shield. You have to micro manage his heat gauge like no tomorrow and he's an deceptively difficult champ to play but has a rewarding playstyle and teamfighting.
(I'd suggest looking into videos and builds and practincing alot before taking this champ into ranked. I don't play him enough to tell you how well he carries or not but that his team fighting is good.)
He does require getting a lot up in the enemies face and usually squishy if you haven't gotten things like Zhonya's or Guise, but can be a real powerhouse for your team.

is pretty much go in and deal damage. She's all physical and packs a... slice? The only problem is that you have to manage her passive and cooldowns properly. It's easy to just do what everyone else stereotypes about her playstyle and just go hamfisted and win but there are some matchups that you'll get punished super hard for being all aggressive without understanding the champions trades. She's tremendously squishy if you go the all damage route but has the potential to carry hard and her bruiser build can't quite carry the her but her CC is helpful here and there. She's very good against teams that have a lot of squishy opponents and that you can delete in one combo. Target CC teams make it really hard for her.
If you want to pick her up and maximize her damage you'll have to understand her animation canceling. You don't HAVE to learn it, but it's probably one of the strongest qualities of her that allow her to do as much as she's able to (trust me it's not hard but constantly doing the cancel in the heat of the moment is not easy). Her biggest downside is that if you lose hard, you're fucked. Like, it's hard to come back from losing lane with her, and that she doesn't fit a lot of the teams needs in most comps.

Has great lane sustain and tends to counter a lot of melee champs because of both of said sustain (from his passive and ult) and Q AD steroid that also reduces AD of the champ he lands this move on. His ultimate also allows him to steal resistances off of the enemies tanks, so during a teamfight it's usually good to use this on the enemies teams biggest tank, making you tankier and them less tanky.
A lot of his kit gives him good fighting power and his E (pillar) is great if used in choke points where you can trap an enemy or mess up their pathing (just be careful cause you can screw yourself or your team out of a kill or potentially get yourself / team killed from a poorly placed pillar)
I don't have much really to say on the champ, just that he has good jungling and laning sustain. He's not a great ganker or even peeler, but is able to reduce AD champs and tanks effectiveness in teamfights. If you like sustain trading then you'll enjoy him, however he's not exceptionally good at carrying.

isn't someone I've been playing much with the new rework so... I won't be able to give you anything worth while on her sadly. Apologies!

is also someone I don't play very often and suck tremendously at. As a Hecarim player you have to be pretty risky a lot of the time because you can't be overly defensive or aggressive with Hecarim unless you're snowballing. Hecarim is the definition of snowball reliant an as such can easily get behind if he's not snowballing a lane or himself. His ultimate is very good in teamfights and the damage and fear it applies makes it exceptionally good. He also has decent wave clear and sustain damage, especially if he gets ahead.
Mostly his snowballing is the biggest factor and can carry early games, but getting behind is not easy for him and late game he falls off pretty hard (but can still be useful with his ultimate). I'd practice a lot with him before taking him into ranked since you'll be finding it frustrating being behind often if you don't get much practice in.

does quite well in 1v1s, but her early game isn't quite that great. She's got minor sustain (apart from her ultimate) and is able to outtrade when her health is below her opponents with her E stun. The E is probably the biggest thing you gotta take into account when going in, if you can land the stun portion before the trade you most often will come out. The slow on it is good but only for chasing. She can wave clear well with her Q reset and ultimate and is ridiculously tanky and able to ignore a lot of hard cc due to her innate tenacity.
She has very good late game power and naturally gets tanky making her very good for carrying games. However anything that can keep her off carries you will struggle pretty hard. She's a decent low level champ to pick up, but her skill is a bit higher than it appears. I'd pick her up if you like mid game spikes.

's sustain damage (I realized a lot of your champion picks are sustain damage oriented) is definitely tricky to deal with. While not very good wave clear post six he's able to get some good harass out his his e + q. He is a good contender for top (though usually fits more in mid lane) if you need some tanky APwhen your mid lane is filled with an ad assassin or ad bruiser (like Jayce) and with his slow tether and ultimate sustain can make it difficult to keep melee champs on him. He can throw a lot damage all over in a teamfight and can be a pseudo-tank with the sustain from his ultimate, allowing you to get all the focus while you back line fires away.
His biggest weakness is mana (+ anything that applies grievious wounds) and you can easily dry yourself clean. You'll find teamfights just a bit difficult if your mana is below 60% and he does not fair too well against dps that is stronger than his sustain. I also don't know the quite the status of his carry potential but generally you can be hard to kill if you can keep your sustain up in teamfights. If you want to be a tanky, sustain, damaging distractor then you'll enjoy him.

I hope these were helpful in some way, I tend to ramble a bit but I hope they made sense for you. I can't really say any of them are for you (since I don't know your playstyle) but most of them fit sustain damage so it might be your cup of tea if you enjoy that kind of thing.
