Malaysia Airlines Loses Contact With 777 en Route to Beijing
Here you cannot see it because the pilot is applying right aileron (probably due to crosswind). So the down flap deflection is cancelled by the up aileron deflection. You can see the outboard aileron deflected up.
Which I think also acts as flap to "smooth" the gap between the two flaps.
(If I am wrong I will have to delete several posts)

In my old days we used to call them "Krueger" flaps.
Today are "flaperons"?
Krueger flaps are leading-edge devices (like the slats).
Flaps, ailerons, and hence flaperons are trailing-edge devices.

[flaperons] We have them on the 747-8 and they are used on take-off and landing and also in a system known as flair assist.
I am quite sure you meant "flare assist".
I normally would not do that, but coming from the official resident spell corrector...
And please do not ever say "wind sheer" either.

Is the green arrow part also a "flaperon"? Pardon my ignorance here, I ask to learn!
The green arrow is pointing to the inboard flap. The blue arrow points to the 'flaperon'. The flaperon is an inboard aileron used for high-speed roll control.
EDIT: Sorry, didn't refresh the page so I now see Gabe and BB already answered your question.

Yes but you confirmed it and worded it differently as well so thanks 2 u 2 !
TThe flaperon is an inboard aileron used for high-speed roll control.
... and also works as a flap.
(sorry, but if not it would be just an aileron, high speed, inboard and all you want, but just an aileron, not a flaperon).

I expected that, by now, it would be known and public whether this part belongs to MH-370 or not.

Krueger flaps are leading edge devices that rotate out from under the wing (a la the 747) rather than extend from the leading edge (a la the 777). The B777 actually does have two small kreuger flaps, one on each wing between the inboard slat and the engine pylon.

Correct, it serves both purposes, hence the name (actually, the outboard 'ailerons' also deploy symmetrically on takeoff to provide some added lift).
But before 3WE accuses us of geeking out on terminology, there is a significant aspect to this panel. It's hard to say what would happen in a fuel-exhaustion scenario without pilot intervention because nobody ever considered it. But if the plane went into a spiral dive and the bank angle protection was still functioning, those flaperons would be deployed up to the full deflection to arrest the roll and in such a dive they might be torn from the wing. Something to consider...
