It is clear to me that "round trip ticket" is used by Americans and "return ticket" is used by those who speak British English.
Tell me about "one way ticket". Is it "one way ticket" only in the USA and Canada or also in Britain?
What do you call it in Britain? A single side ticket? A single trip ticket? or what else.
Does "one way ticket" or a "single side ticket" have different names in English speaking countries? What do you call it in your respective countries?

It's a one-way ticket or a single ticket in BrE.
This would be a natural dialogue at a railway station, for example:
Me: Hi, I'd like a ticket to London please.
Ticket seller: Single or return?
Me: Single please.
Ticket seller: That's £14.80 please.
Me: Oh, actually, I've just realised I need a return!
Ticket seller: OK. That'll be £21.40 then.
In the UK, there are various types of tickets available so I would probably actually ask for a cheap day return, open return, off-peak single, Travelcard, etc.
