I'm new in the photography realm and I want to achieve a foggy/cold/blueish kind of magical look with my pictures. Something like these pics

Please help me! :)

Have you experimented much with photo-editing as yet?

Do you know of that infamous 'histogram' that is often spoken about in tutorials, etc?

That look you've described above happens when the darks in the histogram aren't quite touching the end of the graph. Using whichever method of editing you find most comfortable, that's what you'd need to achieve.

For me, I'd find some sort of software which would allow me to edit the 'curves' of the image, and then grab the 'dark' end of the slider and drag it upward a bit. That low-contrast sort of look will then develop in the blacks of the photograph.

Then, as far as getting the blue tones go, I'd probably go for the white balance setting and carry it more blue that way. Or find the software's colour balance tool and remove a bit of yellow to taste.

Either in the camera itself, or using post-processing software such as Lightroom, you can change the 'temperature' of the colors of the picture by changing a setting called White Balance.

You can there choose to have the colors be more bluish.

There are two main elements I see in your example images:

Contrast

These images have relatively low contrast. The brightest whites are nowhere near pure white. They're light grey. The darkest blacks are nowhere near pure black. They're dark grey. You can do this by reducing overall contrast, by lightening up the shadows (also known as reducing the blacks, depending on your editing application), and by reducing the highlights. You can also use curve tools to do the same thing with even more control.

Color

Rather than doing this with white balance, you'll probably get closer to what you want using an HSL (a/k/a HSV or HSB) tool. Such a tool gives you independent control over the Hue, Saturation, and Luminance (a/k/a Value or Brightness) of different wedges of the color wheel. Most are divided into eight or so channels: red, orange, yellow green, aqua, blue, purple, and magenta or similar. Rather than shifting all colors by the same amount using color temperature and white balance controls, you can emphasize and/or de-emphasize certain colors without shifting all of the colors.
