In case you’re really serious (because the marks above are really minor), marks like that are relatively normal. If you want something to be absolutely perfect, you’re going to have to buy it new and carefully inspect it before buying (as items can get damaged in manufacture, during shipping or hanging in a store). Even then, upon getting the item home and inspecting in a different light, you may find a flaw you didn’t notice in the store.
But buying something new and expecting it to be in essentially perfect condition isn’t out of line — after all, that’s a big part of why people pay extra to buy something new when they could get the same thing cheaper by buying used.
And that’s the thing - used stuff is gonna show some, well, use and no longer be perfect. If you’re intending to actually use (play) these instruments, they will inevitably acquire at least small dings and scratches, even if only played with care at home.
If you like the way an instrument sounds, feels and overall looks, don’t obsess over truly tiny imperfections that one cannot see unless holding the instrument in hand and giving a close inspection. Yeah, the dings, the weird marks can hurt a bit, but if you start to get into the instrument as an actual music-maker and really use it, gain memories with it, go on a musical journey with it, those little marks 1) become much less important, and 2) are inevitably joined by other marks as the instrument gets used while you and it are on that music journey together
