There are many interjections. Some are rarely used nowadays, but are found in books, such as:

Alas! = Expressing sorrow.
Fie! = For shame!
Hark! = Listen!
Lo! = Look!
Pooh! = Nonsense!
Tush! = Nonsense!

Any word or phrase used as a sudden exclamation can be called an interjection. And most of them are shortened sentences. Thus:—

Welcome! = We are glad to see you.
Oh dear me! = What a troublesome thing! or What am I to do?
Dear! / Oh dear! / Dearie me! /  Good grief! /  Lordy! = Expressing pity, shock, dismay, disappointment, sympathy, etc.
Off you go! = Go away! ["You can leave now - Go! - Move! - You're done - You're all set."]
Out with you! =  Go out!
For shame! = You ought to be ashamed of yourself.
Not a bit of it! = It is not so at all.
Good grief! = Expressing surprise.
