I've been playing 
a lot lately and I usually do fairly well in lane unless I'm fighting one of these three: 
, 
, or 
. I'm yet to win a lane against any of them. I just get destroyed. So far, I just roam after my first post-6 back and come back into lane after they're missing and try to take tower. Is there anything I can do/is there a certain way I should play when fighting them?
same as when your up against any counter, you farm, you don't engage until jungle is coming to gank and you tower sit for as long you can. just be mindful of annie q range which is pretty short, see fizz running towards you then hes most likely going to ult and that ur que to zig zag as to make it hard for him to aim, and brand? i don't really see to much of a problem against except for maybe you diving into his aoe accidentally.
Annie is perhaps the hardest counter to Yasuo in the game...it's just a really, really, really bad match up. Fizz is also a decent counter with his pole and what not...both you just have to be amazingly passive. There's honestly not much you can do in the 1 v 1 phase except to try to be passive and go even in CS as much as you possibly can and wait for jungle help to arrive. Both of those champs will roam a lot...so be sure to actively ping your comrades if either disappears from lane...when that happens you need to push and push hard to punish them for the roams.
Brand is a little easier...he pretty much goes even with Yasuo. The good news is that you can windwall both his Q and his R...his R especially travels pretty darn slow so you should be able to block it if you're anywhere close to prepared. Mostly you just have to watch his W/E combo...you're incredibly mobile with Yasuo...so use that to bait his W. Dash out through the minions to either go in after he W's for damage or out to avoid it. He'll almost always follow that up with his E...so just be sure you're out of range of any minion that is still flaming so the E damage doesn't jump to you. You just have to be patient vs him and bait. He's hugely mana intensive....so if you manage to dodge 3 W's...he'll already be hurting.
Regardless of how good the Yasuo is, laning against even a mediocre Annie is very difficult - namely because she has everything needed to render his shield and mobility (basically his strongest aspects) useless. If you're ever against her, I'de either lane swap or play very passively until your jg comes.
Brand is a pain because his long range autos can pop your shield, but I recommend maxing E for the magic damage, running AD runes and jumping onto him when you get the chance. It's honestly not that bad of a matchup as long as you can dodge skillshots, and that just comes with practice. Yas has to much damage output with autos and E max for brand to trade with him 1v1.
In my experience, Fizz is largely dependant on how good the player is. I honestly think Yas vs Fizz is a skill matchup. Remember that you can windwall his ult but thats about it.
