2) Please tell me if this is correct?

A)"If I had $10, wouldn't I give it to you?

B) If I had had $10 yesterday,would I not have given it to you?

Please explain and help me.

Hi!
<"If I had $10,I would give it to you">
This is present unreal conditional.
In this sentence you're talking about present. So you don't have money now, otherwise you would give them to your friend.

<"If I had had $10 yesterday,I would have given it to you">
This is past unreal conditional.
In this sentence you're talking about past. You didn't have money with you yesterday, that's why you could'n give it to your friend. But if you had had you would've given it to your friend.

Hello Stu,

2A and 2B are also fine, as follows:

2a:

"Lend me £10."
"I don't have £10."
"I'm sure you do. Let me see your wallet."
"Why should I show you my wallet? If I had £10, wouldn't I give it to you?"

— thus 2a is a rhetorical question: the speaker is protesting against an unjust accusation.

2b:

"I'm afraid I don't like you any more, MrP."
"Why not, MrQ?"
"Because you wouldn't lend me £10 yesterday."
"But I didn't have £10 to lend you!"
"That doesn't sound very likely. You always have a wad of £10 notes in your wallet."
"What nonsense. If I had had £10, would I not have given it to you?"
"Probably not."

— thus 2b is also a rhetorical question, just like 2a; except that it refers to the past.

Best wishes,

MrP
