See above. Please number your sentences in future. It makes it easier for people to respond if they want to refer to your sentences individually. Note that in BrE, we don't use capitals for "am/pm" and many of us don't use the full stops between the letters. I didn't change yours because different variants of English use different ways of writing this. Here's what I use:

It's 9am.
I start work at 8.45am.
He went to bed at 11pm.

In BE, I'd say

1. I have a lesson from 8.30 to 9am.

2. I have an 8.30–9am lesson.

3. My half-hour lesson starts at 8.30am.

Ah, I took "I have class at 8.30/9 A.M." to mean "I have a class at 8.30am and another one at 9am".

You may be right about that; the OP didn't make that clear.

I was wondering what that meant, too. I've never heard of anyone expressing it that way.

I would write it as follows:

"I have class at 8:30 a.m."
"I have class from 8:30 to 9:00 a.m."

I would say it as follows:

"I have class at eight thirty [a.m.]"
"I have class from eight thirty to nine [a.m.]"

Sometimes I write "am", but I'm afraid that some people, especially learners, might read it as the "am" in "I am".

My class starts at 8:30/9 A.M.

I took it to be incomprehensible. The closest legitimate reading would be that the class started sometime between 8.30 and 9, depending.

I took it to mean the OP was just offering different options for his example.

I did wonder why the OP chose two times so close together, but I supposed it was just to check options that were both on and off the even hours.
