Unidentified Prickly Friends

I have no idea about these things but they seem to flourish on an internal windowsill..can some kind soul identify my Cacti

 

Thanks @Marley Farley...I've had some of them for a few years and nearly killed them in the greenhouse at one stage... I am not sure if the 2nd pic top is an actual cacti but I would still like to know its name all the same.

 

Sorry, not a clue, I just grow em

 

@BigC, I think the second one is a Kalanchoe blossfeldiana ...

Kalanchoe - Wikipedia

 

Thats two of us then hahahahahaha....Tell me about your Home Brew exploits instead then...I've been hearing a few murmurings..

 

This ones been drinking me homebrew

 

Thanks @Victoria ...appreciated

 

I'll have a bash, but cacti are not easy to ID, often the flower helps.
No 1 looks like some kind of Cereus
No 2 Kalanchoe
No 3 could be a very young Ferocactus emoryi
No4 is an I dont have a clue job
No 5 possible Echinocereus .............
No 6 Mammillaria ...............

 

Ooh just the post I need....bought this "cactus garden" off a road side stall in devon this weekend....£2.50.

Any idea what's in it @pete ?

 

Total guess @Snorky85 but..

One at the back sempervivum of some sort, middle prickly pear? Bottom mammilaria? can't see the red to the right tidy and I have no idea about the ones on the left.

 

Thanks @Linz you've got more of an idea than me. I can use the names and look them up now!

 

Tricky, I'm no expert at IDing, if I aint grown it, the chances are I wont know it.
I bought something similar recently to the succulent at the back think it maybe something like Pachyphytum.
A couple of Prickly pears there, (opuntia), the others are a bit small to guess, but could be Chamaecereus.

 

Thanks @pete, youve def got a better idea on me so what youve told me is great thanks.
