From left to right:
1: ferrite antenna. Could be used to build an AM radio. Not a valuable article (new for a few cents).
2. vaccum tube (valve) probably rather used and no longer very useful. Definitely not useful for a novice. Maybe useful for someone dabbling in antique electronics. You'd have to post the full inscription which is not well visible from the photo.
3. I'm sorry, I don't know.
