We use DVCPROHD 1080i50 as sequence setting. Graphics made for fcp are by using Adobe CS 5.5. Sometimes we need RGB+ALPHA. So which video codec shall i use to minimize the render time so that i get RGB+ALpha. Selecting DVCPROHD dont give me that setting.

That's because the DVCProHD codec doesn't support alpha channels. You have to use a different codec. Personally, I like Quicktime's PNG codec for the task -- I can make alpha-channel animations on a Windows machine and use them in FCP -- it's a portable codec, you see.
If you have FCP and AE installed on the same machine, you can use ProRes 4444, which is easier. It doesn't look any better, it's just easier.
Since those would be your two options, the issue of reducing render time comes down to your settings in AE. Since most FCP people blanch at the thought of installing 32 GB on their computers, speeding up your renders could be a challenge. And depending on what you're doing in AE, having that much RAM may not even help. AE's a quirky application.
