Yes, "actually" seems okay. Prettier than my "of course".
But doesn't that sounds like a little weird?
I'd rephrase to
"Each of them, did not look actually like this one.".
I do not know if this is correct, but I think it sounds better that way.
And... what about "obviously"?
"Each of them, obviously, did not look like this one."
Anyway Lein, you are more suited than me to choose properly, as this kinda stuff is outta my league.
We are on the thin line of the English subtlety.
