The mofset has a small metal pad underneath it, whith 6 contact points (contact points where underneath the metal pad connected to the pcb) the metal pad came off with the chip. Which was connected the the unburnt pins. What purpose do they serve?

In the first pic the contact point on the first pin seems to have completely burnt out? Anything I can do about that? Or just pray it still makes contact?

I did not notice any other burnt out chips, only the 1.

Do not worry about the pin that is burnt away.
It is one of the three "Source" pins from the Mosfet.
You still can connect the other two pins to the board, that will do.
The Pin most to the right is the "Gate" and the four pins to the other side are the "Drain" of the Mosfet.
The second Mosfet to be replaced is directly under the damaged one, and is called "4410". This one is a Mosfet with slightly less specs than the 4420, better to use the same Mosfet for both.

The point that you probably refer to as "contact points" are just solder points in case of using a different type of mosfet with a solid underplate "Drain" instead of the four discrete pins, like the ones used for the Vgpu regulation (Q506 and Q510).
So take no notice of these "points", you won't need them.
