Is it possible to delete a file from dump? I saved it in one dump archive, and want to save space by deleting it from the others.

You'd need to write a new dump file, as it models a physical tape, and removing a file would be equivalent to either chopping out a piece of tape (ie. not feasible) or leaving a gap.

You might want to ask this on the dump mailing list at http://dump.sf.net/. Stelian Pop (maintainer of dump) should be able to help with a command to pipe a restore into a dump that omits one file.
