Plz what kind of wood is this or these

Gonna be just a wild guess. You’ll need closer pix of each, preferebly dressed instead of rough sawn.
Looks like a couple of poplar boards and a mahogany board.
Is this pallet material?

Some of it, at least, appears to be black walnut with a lot of sap wood in it.

The third from the right does look like a mahogany. The first does look like a sappy black walnut. The others don’t look like poplar to me (brown rather than green). But in reality, who knows?

Pictures are insufficient quality, long distance, and even then…
