i can only speak for the older ones, but yes you can watch them individually. Though context makes them better of course. Maybe you will feel intrigued and start watching the actual series (rule of thumb: some have rocky early seasons but get much better after some time).
As for discovery, it is definitely very different from older Trek, using a continuous seasonal story arc format made for the age of binge watching, and being very heavy on personal relations and issues.
Would you say one can watch these without context ? (never watched Star Trek either)
edit no I did watch Discovery ! didn’t realize that was Star Trek lol
