Not meteoritic, IMO. However, the stone on the right may be meteorite-related. It looks similar to a tektite: a piece of earth which was blasted out of a meteor crater while still molten, then re-entered the atmosphere some distance away. Try searching for tektites. They look like volcanic glass (obsidian), but have a peculiar bubbly appearance caused by being liquified by force of impact, then solidifying in the air.
No opinion on stone on left.
