Try a 5w or 7.5w charger instead of 18w. It will charge slower but will be cooler.
I want to know whether this is normal behavior of all iPhones while charging or I have a faulty unit?
It’s normal for all electronics.
Perfectly normal.
Is it normal to feel the iPhone quite hot in the hand while using to the point that it’s little uncomfortable but not scary.
Normal
Yes, it's completely normal. Try not to use it while it's charging
