Here is what I see.
The original 03 springfield would go from $500-$1000 depending on matching numbers, bore condition etc.
The 03 sporterized would go for about $500, actions alone sell for about $300 and up.
The SAvage 311, I have one like it, would go $300-350
The ranger single shot, $100-150
The exposed Hammer shotgun, if barrels are tight and in good shape inside, would go at least, $250 here for a wallhanger and up.
The mossberg bolt action shotugn would top out at about $100 here, most folks wont give them a second look.
The Galesi would go for $200 or so, here, saw one sell at a recent gunshow for this, in the box unfired, might go a bit more.
The Colt would be thru the roof, Colt collectors would be lined up. I would think about $1200 up for this one, would need to see it more closey, see the model and year references.
These are real market values here, as I see them, ran a gunshop for a long time, but markets fluctuate, and economy has impact on it also. Nice pile of guns, would love to have them all.
