Should I be correcting any of this?

I agree. It looks like my two. Mine are about the same ages as yours. Once in a while the pup overdoes it and Jack gives her a "prong" teeth correction and all is well. She will be back at him soon enough.
I do give them breaks from each othe though. Mostly for Jack. He is 5 now and loves playing but does not wish to do it all day long. She is 4.5 mos. and would play for hours.

If she didn't keep him in line he'd be a terror. So she's doing a very good job playing mama with him.

I think your dogs are doing great. The little guy is being a pest but that's what puppies do. The older gal is handling him firmly and teaching him how he must behave. The only thing I would do differently is to feed them in separate rooms or at least one of them in a crate so they each can have absolute peace while eating. Serious fighting over food is much easier to prevent than to correct once it starts. Food is very important to your dogs. Let it be completely enjoyable without the stress of the puppy crowding her dish.

I actually love having an older guy or gal in the home who will do this with puppies, especially puppies who missed critical time with mama for whatever reason. They can teach critical dog-life skills that humans could never replicate.

Well I feel a lot better about it now, thank you! Its hard to tell if it's an ok thing or not. I was worried I wasn't doing something that will make it horrible & uncontrollable when the puppy stage ends.
So this does include her grabbing a toy when she thinks he wants it?

and Knuckles did miss those last 3 weeks with mom! Saki became "mom" when he was 5 weeks old.

Yes, her taking "his" toys is fine. To him, they are nothing, maybe something he wanted to see, but to her, it's "class time".
She's schoolin' him and you just stand back and marvel.
He will be a much better behaved dog than had you brought him home and had no other dog to teach him these things.

Zena, our puppy wants whatever Jack has. Which is another reason I give them breaks from each other. He's actually very good about sharing. I do feed apart from each other so they each can eat in peace.

We overcame the ball throwing issue this way:

Niko must be in an informal sit-stay and wait his turn (I tell him "Niko, wait."). I say "Ready Rosa?" and she knows this ball is being thrown for her. I throw the ball, she chases...

While Rosa is out getting her ball, I say "Ready Niko?", and Niko knows he can get out of his sit-stay and I throw his ball in the OPPOSITE direction of where I threw Rosa's ball.

It took a while for everybody to catch on, but now they know if they just wait a second, a ball is going to be thrown specifically for them.
