Any of those should work, you're looking for DDR4 2133MHz, also known as PC4-17000. You have 4GB soldered to the motherboard and a stick of 4GB installed in the only available socket, it would be dumb to get the first one as you'd end up with the same amount of system memory.

Because part of it is soldered, the maximum amount of memory your laptop can have is 20GB (if you install a 16GB stick), but you could sit at 12GB with a sitck of 8GB for example.

As for the M.2 port, the only thing definite I could see is that there is an M keyed socket in there, but no info on whether it's NVMe capable or only SATA. You should look for a Root PCIe bus that's capable of x2 or x4, that would be an indication that it's NVMe capable:

This link says I need 2400MHz ???

It depends on the processor and what you have installed, your PC has an Intel i5 7200U. Per its specification sheet, it supports DDR4-2133, LPDDR3-1866 and DDR3L-1600; but all of them have different sockets (e.g. you can't install DDR4 in an DDR3L socket).

So you needed to look at the one you have installed right now, which seems to be DDR4 at 2133MHz. Many memory capable of operating at higher frequencies also have timing specs for 2133MHz so they'd work at that speed in your machine instead of the one they're advertised as, but ideally you'd need to get DDR4-2133.

There's a PCIe 3.0 x4 link that's unpopulated right now (per the HWiNFO report), that has to be wired to the M.2 slot so NVMe SSDs are supported ^^,
