Just above the Browning Auto5, the small semi-auto rifle might be a Marlin 60 in .22 cal. Doesn’t look beefy enough to be a Ruger.
I think you are correct. It and the one with the tiger striped stock both look like model 60 variants to me.
The bolt gun with the wider stock and the slightly reduced tip of the forend is a Mossberg model 42, I think.
