HTC SDK API Level - 5.69
Baseband - 1.13.3230.xxxxxxxx
My Problems -

2) could I able to get Lollipop ?
3) How to find out my phone was Original or Not ??
Please help

It looks like you've got the Chinese variant. if so, you can look it up in the forum, there is a way to update your phone to the latest ROM. no lollipop is available for any variant of 816 yet, but if an update comes in the future, you will most probably be able to use it.

To get lollipop you could flash CM12, but it wouldn't be official lollipop from HTC.

Thanks all My buddies ! :fingers-crossed::fingers-crossed::fingers-crossed:
