I am connected to my friend's WiFi hotspot (the hotspot is on a laptop with Windows 10). How can I find out his IP? Is it even possible? I have tried to use Wireshark but I have no idea how it works.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
If I understand the question correctly, your friend has a laptop with an External Internet connection of some sort (cable modem, 4G, etc probably over Ethernet) and is sharing Internet via his wireless adapter.
To find out his laptop's wireless IP address from your wireless device, look in the device's network settings for the "Router". On a Mac, it's System Preferences->Network->WiFi->Advanced->TCP/IP->look for the "Router". I don't have a Windows 10 device with wireless to give the exact GUI steps, but it should be similar.
To find out his laptop's wireless IP address from his own laptop, look in the same place for "IPv4 address".
