Were Ali the first to use these moves?

Good work compiling the clips.
To answer your question, no I don't think he's he first to use those moves.

I will look for examples in a bit.

 

The way he dodged those hooks is just silly. Don't try this at home !!!
I don't know if that's skill or stupidity or magic, to be honest. He got away with it somehow.

The pull back and counter with the right hand is a lot more plausible. I can buy that as a move.

Yeah, I'm guessing a guy like Tony Canzoneri would be doing stuff like that. I'll have a look.

 

Much of Ali's style was modeled after sugar Ray Robinson whom he greatly admired.

So, in all the examples you provided, what Ali is essentially doing is a backwards slip that offsets the opponent, that he follows up with a clean counter.

Almost every fighter has done some type of this.
To illustrate how all pervasive this technique is, here is Max Baer doing what Ali does to Frazier in your second clip.

He slips backwards, twice actually, and make's the guy pay with a counter from the outside.
Obviously, he doesn't have the same grace or sharpness as Ali, but he is performing the same action.

Here is WIllie Pep pulling back and landing a counter jab.

Another Pep example.

Randy Turpin Pulls with his hands at his sides, and counters with two hard punches:

Notes:
- Nobody looked smoother at this than Ali.
- The more subtle the move, the less impressive it looks with older film.

If you look closely, most fighters do this kind of thing.
Even George Foreman had some nice pull counters.
However, I do think Ali popularized them.

 

Robinson would often slip shots and counter with combo`s to the body, one of the main fights where he used the hook a lot as a counter was the 2nd Fullmer fight, someone replied to me on youtube saying how the preparation Robi had for that fight in terms of tactics was a plan called operation left hook.

 

I don`t really think you can compare Bowe`s defense with McCallum`s, maybe he did slip or ride shots but not often enough.

 

I'm not sure that's what Ali does there though.
Maybe my eyes are deceiving but what I see is ..
He dodges the Bonavena punch, cartoon style. Makes it miss. And the way he's leaning back makes it imperative that it does miss, since his head is in no position to ride out the punch or dissipate it if it were connecting. His chin is not down and his body isn't swaying the punch out. It's a fraction from disaster. It's a really bold move.

Yes, the counter punch is brilliant. One of the best he ever landed, and that's saying something.

 

Nobody is ever the first to do a given move in boxing.

Whenever you think that you have found the origin, you will always find it further back.
