I built with bracket and servo AX-12A, But its very heavy so the body can't stand..Any other solution to chose the servo and design it

Legs & hips require double the torque power of the upper body. You'll need larger/stronger servos for it to move properly...

thanks for your suggestion, but i stuck design it, can you tell me reference to design the humanoid robotic sir,,

OK, looking over your design again, it looks like you've over extended the basic design... It's still a torque issue. the simple 'bioloid' servo & bracket build has it's limitations, & is dificult to expand on. Making it bigger adds more weight, which requires larger servos & brackets, which add more weight... You get the picture.

If you are trying to build a larget bot, you need a self-supporting frame which uses the servos just for movement, and not as weight bearing parts...

Here's a good example of a functional bioloid-
