Hi, a friend of mine is about to go to United States(I’m from Israel) and I asked of him to buy me an Apple Watch series 5, but I would like to know, if he buys it in the US will the cellular work in my country?(Israel)
Apple Watch
No.
Cellular Carriers that support the Apple Watch, which models, the radio frequencies each model uses, and the country where they offer service:

You will the U.S. uses a different model with a different cellular radio from Israel.
Your Israel carrier will not attempt to pair a U.S. Apple Watch with your iPhone.
Your friend can get you a GPS only Apple Watch which will work anywhere in the world that your iPhone works. The GPS only model will do Everything the cellular model will do as long as your iPhone is nearby. The cellular model can leave the iPhone at home while you go for a run, bike ride, etc...
What the Apple Watch GPS-only can do without an iPhone (there is information about the cellular model as well)
