i have 2 powerbanks, they both have x2 outputs of 5v 2A and 1A, so total 4 outs 2x 5V 2A & 2x 5V 1A

I need something to convert this into 12V 2A so i can power my small notebook

Can you help me with this?
is it possible ?

Just about possible. 30W power available, and 24W power needed so the conversion would need to be at least 80% efficient which should be possible with some arrangement of switch mode boost converter(s). I don't know just how that would be arranged though.

To boost the 5V supplies up is not the best way to go. And it sounds like they would be running over max current anyway.
Go to a second hand junk store an pick up a power supply there if you can find one. 12V at 2A should be fairly easy to find.
Are you sure the notebooks is 12V? Most seem to be 19V now.
