'Royal gas' is not a term used in chemistry. Perhaps you mean "noble gas", if so yes "inert gas" and "noble gas" often mean the same thing. However, oxides and fluorides of some of the "noble gasses " do exist, it might be best to think of them as "noble" rather than "inert". Xe, forms oxides.
Noble gases or the inert gases as they are become know as have a full outer shell. It is possible to get different elements to fill in the last outer shell but it is extremely difficult to take electrons from a noble gas therefore when you ask what the difference is the question is perhaps not phrased properly because there is no difference they are two different categories. A noble gas is an element with a full outer shell and full outer shell is when an element has filled all of the max electrons in the last orbital.
Argon is called a noble gas because it is very stable and does not easily react with other elements to form compounds. This stability is due to its full outer electron shell, making it chemically inert. This characteristic is similar to noble or royal behavior, which is why argon is called a noble gas.
No, it is a noble gas
There are no "noble metals". The "noble" connotation for "noble gas" is that in society, the "noble" people don't interact with the average people. "Noble" or inert gases do not take part in any regular chemical reactions. The individual atoms don't form elements or compounds.
Noble women are women who are related to a royal family.
The opposite of "royal" is "common", as in a commoner - a person who is not a noble.
