[Grammar] since ten years ago

Could any native speaker advise me if the following uses of prepositions are correct grammatically or in daily English speaking?

1. It has been raining since one hour ago.
2. It has been raining from one hour ago.
3. It has rained since lunchtime.
4. It has rained from lunchtime.

Welcome to the forum. Heewoo.:-D

Only #3 is correct.

Bear in mind, though, that 3 means that at some point since lunchtime, there was at least one period of rain. It is no longer raining. If it started after lunchtime and is still raining, use "It has been raining since lunchtime".

See above.

What did you want to describe in terms of the rain? Has it finished? Did it start one hour ago?
