Why 11 am + 1 hour == 12:00 pm?

ᴛʟᴅʀ: Virtually all style guides tell people to stop using the irresolvably ambiguous twelve o’clock ᴀᴍ and twelve o’clock ᴘᴍ in favor of twelve o’clock noon and twelve o’clock midnight. That solves ...

Would it be "went to sleep at one yesterday" or ”...today"?

This is not a matter of grammar but of semantics and idiom. I don't think most native speakers would use either "today" or "yesterday"; we'd say I went to bed at one o'clock last night or I went ...

Why 11 am + 1 hour == 12:00 pm?

I agree that for the precise moment of 12:00, adding PM or AM is a bit arbitrary. However, imagine we add another minute: 12:01. If this is the time that is 1 hour, one minute after 11:00 AM, then ...

Do I need to say “o’clock”?

No. When it is clear you are talking about a time (as it is here) "o'clock" is optional, and often omitted. So "From 9 to 10" would be the common way of reading that. Your second example is most ...

Am I telling the time correctly on the analog clock?

Those are nearly right, but when it's not a multiple of 5 minutes we almost always say the word "minute(s)". So: It's two minutes past one. It's twenty-six minutes past one. It's twenty-...

Why 11 am + 1 hour == 12:00 pm?

In traditional time, we have two times that are labeled 12:00. We define 12:00 A.M. to be midnight and 12:00 P.M. to be noon. The latter is of course technically inconsistent with the original Latin ...

Yes, the word "day" can mean the entire 24-hour period. But it can also mean just the part where the Sun is above the horizon. It can also mean the part of the day during which work and other "daytime"...
