I'm going to assume that by posting these, you're looking for feedback.
I could do what is often done and say something insipid like:"Nice - they should clean up fine and be great users"
But instead, I'll be honest with you - 20/each is quite high. The number four is a very late model plane (possible even UK-made) It dates to a time after Stanley quality had declined greatly.
The No 5 seems to be sporting stained hardwood handles, rather than rosewood, and may not even have brass fittings.
That said, they probably will make good users.
The point here is not to make you feel bad, but to educate you.
All of us go through the learning curve.
