ID help please

[shallen]

hi I'm new to the forum

could you guys please help me ID and or confirm the id these cacti I have been given

the cacti in the first 3 pics I'm having the most trouble with as the pup looks so different to the mother plant all the person i got them off could tell me was that they have white saucer sized flowers

and from what google tells me i think the cactus in the 4th and 5th pics is a peruvianus

and the cactus in the last 2 I think is some variation of a pachanoi

Any help would be much appreciated
