I need help identifying a few cacti and succulents

[BC/Cacti]

Hello, I need help identifying a few cacti and succulents, I have numbered them 1 to 5 to make it easier.. Thank you for your help, number 1 has soft spines from growing points and when cut it bleeds white milk..

Any help would be very much appreciated. Thank you.
Kind regards BC/cacti

1. Euphorbia sp.
2. Carpobrotus edulis ?
3. Kalanchoe sp. ?
4. Aloe sp.
5. Crassula ovata

I think 3 is Cotyledon orbiculata, 4 is Aloe mitriformis.

Euphorbias have characteristic white milky sap - this is toxic and caustic in most species so be careful if you come into contact with it.

Thank you very much. I will research all mentioned to get a positive ID. I very much appreciate you taking your time to help me in identifying.

I'm having real trouble identifying number 1. It seems like a Euphorbhia, I just can't figure out what species of Euphorbia it is. There is over 2000 Euphorbhia specie's making it real hard for me too identify it. Thankyou.
Kind regards, BC/cacti

Lots of Euphorbias look pretty similar!
My guess would be E. polygona, but I wouldn't get too hung up on an exact id - I'd bet the care is similar to this species.
You could check which plants your local nurseries stock and try to match this to their selection.

Ok. Thankyou, I just posted some more pictures of it and described it in more detail.
