Re: "himself" and "by himself"
In #1, the emphatic 'himself' emphasises that he, not anybody else, cooked the dinner.

While the constructions are different, the overall meanings are similar.
You can, but it seems to add even more emphasis. 'Himself' would be more commonly placed at the end.
Can I put "himself" in the first sentence at one more position? (such as "He himself cooked the dinner").
That does not sound very natural to me.
... in the second sentence, can I say "By himself, he cooked the dinner"
