I need to analysis some x86 dump file, So I want to install the x86 windbg on my computer.
or if I can use the x64 windbg to analysis the x86 dump file?

Yes, and it is a good idea to do so since you'll need the 32 bit version to debug 32 bit applications/dumps. All the files are located in the install directory, so you can have any number of installations side by side.
Also, keep in mind that if you use a 64 bit tool to create a dump, you'll get a 64 bit dump - even if the process is 32 bit. In that case you'll get a dump of the WoW64 process, which makes debugging the dump a bit more difficult. However, if you use a 32 bit tool to create the dump file, you'll get a regular 32 bit dump and then you can use the 32 bit debugger as you normally would.
