I wouldn't be suprised if the first wasn't a roo, look at those thick legs! Secound I'd say hen but I've heard EEs and peacombs can be hard to sex, although I'm not seeing very roosterish coloration or feathers from your pics.
Ahh yes ChocolateMouse is correct btw, those are both EE's. Real Americaunas are actually somewhat rare as they have strict formation/trait standards like a rag doll cat vs a raggamuffin look very similar but certain colors or small physicalities can define the difference
People assume my cats a ragdoll but due to his coloration and same minor differences in shape size he's defined as a ragamuffin although they act almost the same and he still does the 'ragdoll' routine when handled
I'm going to vote for 2 roos. At 9 weeks, no hen should have a comb that large and red (#1). #2 is a little harder. My pullets at that age had pale yellow combs, not pink. If you look at the tail feathers, the topmost ones appear to be slightly longer and starting to curl downwards. It's legs are rather massive, however, I'm only noticing that in relation to all the other things. As they get older, males will get longer feathers on their (lower) neck (hackles) and on their back in front of their tail (saddle). The top tail feathers will elongate and start to curve down (like a ponytail). Perhaps the easiest way to tell: they will start crowing any time! Good luck!
Heres my 2, now one, as I sold one boy just this morning! EE roosters at yearling age. A rooster whith adult feathering will have Sickle feathers that are notably longer and sharper to any hens rounded edges & that pea comb will also swell in size and turn vibrant red. My boys haven't grown spurs yet, although my polish hen ironically has XD thought she was gonna be a he for about 2 months until she layed an egg. They may be more colorful at adult feathering as well whith can also imply sex depending on what coloring it is.
For #2, I think you should wait a few more weeks before deciding. It is sending mixed signals. My guess is that it is a pullet that just happens to have thick legs, but it could be a slow developing cockerel, too. Time will tell.
