Number six, looks like agatized Petrified wood. Probably from Arizona

Number five looks like yellow Quartz

Number four is a concretion.

Hopefully some others can help. I have to go but I'll try some others later.

Number 3 looks to me like clear quartz cluster of points with horizontal striations. One pair are visibly bridged into each other. Not sure of the geological term but these etched lines are sometimes called "barcodes"; esoteric descriptions apply "lemurian". Found in Sierra Do Cabral Mountain in Minas Gerais, Brazil.

Number 2 is likely a massed cubes formation like fluorite (Moh's hardness 4). Is it black-purple? If it's black fluorite that's one of the rarer colours.

Actually number 4 has coloring and crystal shape that would indicate galena. And number 5 looks more like calcite in terms of habit and coloring, although a better picture could better indicate that.
