Okay, firstly, welcome to the forums.
Secondly, I shall answer your questions.

Quote: "How can I add a health bar for enemy?"
This is a system that has not yet been scripted on my recollection. You can, however use your own health bar. Unfortunately you will require Plystires Mod in order to do this.

Quote: "And I want the loading bar goes faster and the game load faster."
The loading bar goes at the same speed as the loading process of the engine. The loading bar is generic, it will usually stop moving when it comes to a point in the loading process where a serious process is in effect e.g Lightmaps. If you want to make loading times faster you should download the newest update of FPS Creator. Either that or you could upgrade your hardware. Most likely the processor, since it will do most of the actual processing, hence the name.
Please expand if I haven't answered what you wanted to hear.
