Slide One:
One punch from one of Yaga’s Dolls, physically affects a Yuji that should have around Grade Two stats.
(This Doll shouldn’t be going all out either, since they weren’t trying to end Yuji)

This punch still physically affected Yuji, even though the Doll punched the backpack, which means less force would be applied to Yuji.

Slide Two:
The Doll blitzes Yuji with ease.
The ram also knocks Yuji back a decent amount.

Slide Three:
A punch from the Doll, sends Yuji flying back.

Slide Four:
Even though it was a two v one, (which we know is a big thing in JJK) Yaga was able to break Gakuganji’s Guitar.
Gakuganji is also visibly damaged.

I’m assuming that Gakuganji is around a Grade One’s strength.
(No i don’t have a reason for this, it is purely going off vibes)

I’m assuming that the other guy is around Grade Two.
(Again, pure vibes)

Yaga didn’t use his Dolls against them as well.

So for the agenda’s sake, this means that Yaga should be a mid tier Grade One on his own.

We know that Yaga has a lot of Dolls.

For the agenda’s sake, I’m also going to assume that each Doll is around the same strength as the one that fought Yuji.

So let’s say Yaga has three Dolls with him.

A mid tier Grade One, with three around Grade Two level Dolls, would be pretty strong.
And that’s only three, we see that Yaga has way more.

Is a lot of this assumption based?
Absolutely.

Does it matter to me?
No.
I have an agenda.
Which means I’m going to push it.

In Conclusion:
Yaga beats Higuruma.

Yaga lowkey built like that.
