can vs could

Non-PRO English Other Other English Grammar, Murphey
I have a question about using CAN and COULD.
Unit 37 of English Grammar in Use by Murphey says
: "We also use could (not can) to say that something is possible now or in the future:

1. The story could be true, but I don’t think it is. (not can be true)
2. I don’t know what time Lisa is coming. She could get here at any time.
3. The weather is nice now, but it could change later. (the weather now, not in general)
4. The company Amy works for isn’t doing well. She could lose her job.
5. Be careful climbing that tree. You could fall.

I just want to check if it's really so now, that is in the contemporary English language.
Or could use 'can' in at least some of the above sentences?
Thank you in advance.

Tony M Aug 1, 2022:
@ Asker One rule-of-thumb test you can try is to see if the 'could' can be replaced using 'might' — i.e. expressing the doubt found in the 'conditional' tense.
In the very last sentence, it would be possible to use 'can' with a slightly changed meaning — perhaps expressing less doubt: "You can fall." = it is possible for you to fall; but this would be the less usual usage in normal EN.

No can do

Could is correct in all those sentences. Can won't work.

can won't work in any of those sentences

In each of the sentences there is a possibility of something (happening, being at a certain state, or not) None of them argue ability or talent.
