I am really confused in digesting Japanese tenses while referring to English tenses in mind. Is there a list mapping each English tense to Japanese one?
Please kindly also provide us with some sentences per tense.
"Is there a list mapping each English tense to Japanese one?"
There is a simple answer to this question: No. Unrelated languages, like English (or any other Indo-European language) and Japanese do not have corresponding sets of grammar functions, so it is not possible in any meaningful way to map one to the other.
It may sound hard, but you have to learn how different bits of Japanese verb morphology ("endings", in other words) work, and work on hearing enough Japanese that you understand it. Whether or not you can immediately give "English replacements" for the bits is largely irrelevant, and if you struggle through trying to pretend that each Japanese structure has a corresponding English structure, you will have a very hard time as you keep bumping into the fact that this is not true.
I hope this helps; that is my intention, but there are many people around with other ideas -- for example that everything is about "translation", which I think is a way to make things even more difficult than they already are.
