Hello. I have three cacti and no clue as to what kind they are. I inherited the tallest one (bottom right) from a family member and bought the other two from a local nursery where every cacti has a tag that says "cacti" and nothing else.

Some details that you can't see in the pics:

The tall, flowering cactus has clusters of 14 spines with one larger, hooked spine in the middle. The middle spine has a reddish, brown color close to the plant. It is spiral.

The small white-spined one (bottom left) is about the size of a quarter and has a small dip in the top center of it.

The smaller cloumnar (top left) does not spiral.

Both tall cacti have 12 ribs.

The two cacti not picutred with flowers have never flowered, so no help there.

Any ideas? Thanks :)
