Let's say my friend has bought a phone. And I want to buy the same phone, not from my friend, but at a phone store. Is natural to ask my friend how much is the phone? Would it be more natural to ask him how much does the phone cost? I think that you ask the question hom much is something only when you are at a store asking the shop assistant about the price. Being a non-native English speaker it is hard to tell whether the question how much is something sounds natural when you are asking your friends.

Indeed, if you turn to your friend and ask him
How much is this?
It sounds like you are asking him its price, as if he were to sell you. A better approach would be
How much did you pay for this phone?
How much was it?
