4.

Assuming you are using Windows 10:

Open Chrome and click on the three dots in the top right corner of the screen. Click on Settings.
Under the "On startup" section, click the radio button next to "Open a specific page or set of pages".
Click on the blue link that says "Set pages".
In the popup window, enter the URL of the first page you want to open in the first field. In the second field, enter the URL of the second page you want to open. Repeat this for the third and fourth fields.
Click OK.
Close the Settings tab.

The next time you start Chrome, it will open four tabs, each in its own window, in the corners of your screen.

If you need to open 4 windows of Chrome on startup in each corner of your screen, here are the steps to do it:

Right-click on the desktop and select New > Shortcut.
In the Create Shortcut window window type “Chrome.exe –new-window --window-position 0,0 --window-size 500,500” in the location textbox (without the quotation marks). This will create a shortcut to open a Chrome window in the top-left corner of the screen, with a size of 500px by 500px.
Now go ahead and create 3 more shortcuts using the same command but changing the last two parameters each time. To open a Chrome window in the top-right corner, type “Chrome.exe --new-window --window-position 500,0 --window-size 500,500” and so on.
Once you have all four shortcuts created, they can be placed in the Windows Start up folder to open on startup. To do this, hit Win + R to open the Run window, type “shell:startup” (without the quotation marks) and hit enter.
Copy all four shortcuts you created into the startup folder.
The next time you restart your computer, 4 Chrome windows should open each one in its respective corner.

I hope this helps!
