Also, do i need to check-in again if connecting flight or I can just go straight to security and customs? I remember they already issue a boarding pass on the 1st leg.
If you have an onward boarding pass you go to the closest transit security checkpoint from your arrival gate. Be aware that you may not be allowed through as you don't have a 'same day' boarding pass.
If you do get through, you need to allow plenty of time to be escorted through immigration to get back landside. This is not something that is encouraged as it takes resources and someone has to stop what they're doing to come get you.
In all seriousness, the CX biz class lounges are not worth the hassle of doing what you propose. And added to that you'll then want to find transport to your hotel at 1am in the morning. It will be much easier just to go straight to a hotel, have a good rest and be ready to enjoy the lounges in the monring.
