Q: Income と Salary と Pay と Payment と Hourly wage はどう違いますか?
A: Income is monies going in. It is not limited to salary.

Payment is the amount paid to a person or company for a service, product, or work.
ex. Payment for the complete cost of your hospital bills have been made.
ex. Payment for grooming services are due this Saturday.

Is this ever beautiful scenery!
A: Most of these sound natural.

"I won’t be amazed at what so ever happens in this world?

This one sounds kind of strange. "I won't be surprised at whatever happens in this world." would be a little better. Or "Whatever happens in this world, I won't be surprised."

"Is this ever beautiful scenery!

Here it might be better to use "This is very beautiful scenery!" or "This scenery is so beautiful!"
