7 Cacti IDs plz

[flamekitty84]

So I just went to CVS the other day and they had some cute lil cacti for $1.99 each... I picked 5 of them and brought them home to put with my other babies.
Lo and behold, not a single one had an ID on them...So here I am with 5 nameless cacti, but I just couldn't pass them up!
So the first 5 photos are the 5 I bought. The 6th pic is a cactus I got at home depot or something...This one is actually labeled as a 'succulent' but idk how accurate that is. I IDed it myself as a Golden Torch, but I just want to be sure.
The last two pics are a pad I picked from a neighbors yard. It looks like a prickley pear, but the spines are soft and fleshy. Also, the big plant itself, which I did not happen to get a pic of, actually had big random spines poking out in clusters. I don't know if I want to say its a prickley pear simply because I do not see these spines on the prickley pear pictures I looked through.
Any help would be appreciated!! Thank you!

Those fleshy things on your pad are typical of new prickly pear pads. I have read in layman kind of wildflower books that these are actually the leaves of prickly pears. Later they will be replaced by spines. It is my understanding that the pads are biologically the trunk/stem.

Never have watched close enough to see if the spines literally develop from the fleshy stuff or if they grow out and push the fleshy leaf off.

As you say those are the leaves Opuntia's produce Bonnie. They do not turn into spines but are fugacious, a posh way of saying soon fall off (Botany fugacious = falling or fading early). They are probably at their most developed in some of the cylindrical Opuntia's:-

As you say the pads are flattened stems (cladodes) and in some genera like Epiphyllum, Schlumbergera etc people often mistake them for leaves, but leaves never produce flowers. Think of an Opuntia pad, or Schlumbergera (Christmas Cactus) joint, as a flattened two ribbed stem. The spines on Opuntia develop later, independently of the fugacious leaves.

The name "Prickly Pear" is applied to most flat padded Opuntia's irrespective of species, so is not diagnostic.

Number 3 is an Espostoa

Number 4 has a false flower stuck on it

Number 5 Oreocereus

yes I am aware that is a false flower. do you know what the actual cactus is?

I will call the pad a prickly pear for now and just see how it grows, if it does.

4 looks like a Polaskia chichipe

I think #2 is Echinocactus grusonii. #1 is very familiar and common, Echinopsis sp. perhaps. I just can't place it.
