Answer

না is used for questions. Do you like this or that? = তুমি এটা পছন্দ করো না/নাকি ওটা?

Answer

অথবা and বা are used interchangeably. না is used only in a question. All three mean the same.

Answer

বা, অথবা, না, কিংবা, কি, নতুবা, না হয়, নয়ত, নয়, নচেৎ, নহিলে। All of these can be used in different cases.

Answer

the  বা and না is rather used in speaking bengali....but in written we always use অথবা।
না is always used in interrogative sentence..
না- তুমি যাবে না আমি যাব?
বা - লাইব্রেরীতে যান বা বাড়িতে যান(colloquial)
অথবা- লাইব্রেরীতে যান অথবা বাড়িতে যান(written)
