1-) I wanna know is there's any way to install vCenter 5.5 or vCenter 6 on Windows 8 ?

2-) Surely I can install vCenter on a Windows server 2012 R2 inside my VMware Workstation and here's my question now I can install vCenter with 4G of RAM allocated to my Windows server However it requires 8 Gig and it works fine Now wanna know can I install vCenter on windows Server
vCenter 5.5 requires 4GB and vCenter 6.0 requires 8GB, anyway you can allocate more memory to your virtual machines than you have physically and VMware Workstation will swap some part of memory. See: Configuring Additional Memory Settings
3-) When I add data to my Windows server inside the VMware workstation let say additoinal 4 Gig of Data surely virtual Hard Disk will increase BUT when I delete that data the virtual Hard disk remain the same size on my physical Hard Disk How can I solve that problem ?
This is not a problem and the expected behavior. If you want that space back, you can use the following procedure: Clean Up a Virtual Hard Disk on Windows Hosts
