Is there any method for python plugin in QGIS 2.8 to support multiple languages.(including .ui files that is call from this python).Please anyone can help i am new to this environment


From what I understand, you are trying to support internationalization in a plugin you are developping. It is possible, although not very well documented. Please have a look at this answer which contains relevant information and links : https://gis.stackexchange.com/a/176200/64955.

In short : the best way is to look at other plugins. You have to create a .pro file in a i18n directory, then use QT 4 Linguist to provide your own translation (this will create a .ts file), or (alternatively) manually create a .ts file. Finally, run lrelease to generate a .qm (compiled) file.

If you edit your plugin (either .py or .ui files), you will have to run pylupdate4 to update the .ts file, then lrelease to update the .qm file.
