Hi @satez416 and welcome to Tatoeba!
A couple of things:
1. Generally, we put one sentence at a time on Tatoeba, separately.
2. Punctuation is necessary for English sentences, and for any language that uses it.
So here you should have four separate sentences:
Hi!
Greetings!
ಹಾಯ್!
ನಮಸ್ಕಾರ!
Thanks for changing the sentence. However, there should be no space between "Hi" and the exclamation mark:
Hi!
