Is income salary? or is it the *take home pay* after tax deductions are made? and if it is the second one, then is income the same as *net monthly salary?*​

Yea salary typically makes up a persons income
Yes take home pay is after deductions. Usually differentiate by gross income and net income.

Net income would be the same as net monthly salary and take home pay.

Basically you get paid a salary and that that is gross income before deductions. Then money is taken out for taxes insurance retirement etc, and whatever is leftover is your take home pay or net income or net monthly salary whatever you wanna call it. Neto take home means after deductions
