Is there anyway to combine asian fonts like chinese, korean or japan fonts with english fonts then export as ttf? I heard that Adobe Framemaker can make this but is there any other way without Framemaker?
Is seems that you are referring to a Unicode TrueType font?
There are some fonts (such as Arial Unicode MS) that are mapped to the Universal Character Set or Unicode, which allows them to store a glyph for any Unicode / UCS character. If you create a font that supports this, you will be able to use one font for characters from multiple languages.
Font editing software can probably be used to combine glyphs from multiple fonts to produce a new font (where font licences permit)
e.g. Fontforfge, Fontographer, etc
The task may require you to learn more about fonts than you wish to know.
