Josh is short for Joshua, which means "God saves" or "God is salvation" in Hebrew. Allen is a Celtic name that variously means "little rock," "harmony," or "handsome." If there's a similar name/word to Allen in Hebrew, I'm not aware of it.

Edit: Just saw your post further down with the Hebrew word. Interesting.
