Girl avoids me when I greet her. I waved at her and she truly noticed my attempts of greeting her but she hid inside her house is she shy or avoiding?

Perhaps you should take a hint when you see one.

You have received now three of them which obviously you failed to analyze properly

1. A reply such as "perhaps another time" or "later" is indicative that she does not really want to give you her number.
2. A wrong number is also a hint that she hopes you don't call.
3. No reply on a text is the final attempt at getting the message across

You seem to want to insist on a lost cause. She is not shy but only uninterested in dating you. You practically twisted her arm to give you her number but obviously she did it unwillingly. If she greets you, you will believe that she is interested in you and you will only insist even more and that is why she refrains from waving back at you.

Time to move on and find someone that does not give you such obvious signals.
