All these seem to be atleast 18 months older. There are surely better models than these at the same price. 
  
 What is your use case?

Daily activities

 Multimedia good to see 
 Battery fast charging 
 Photos should be best

Samsung: you wont get fast charging, but very good photos 
 Redmi: Processors are mid range, so multi tasking and performance is not best 
  
 Better to go with Iqoo Neo 7pro or the new neo 9pro, whichever fits your budget. Good photos and best performance and screen. 
 Neo 9pro has SD 8Gen2, it will do anything you throw at it till 2028 and beyond.
