Hi, Thank you. I have three more questions.
1.Why is that we can't say "If I have money, I could use it lend it to my friend" but can say "If I have money, I can use it to lend it to my friend'?
I think those are the same forms except the that one or those ones used before are in question forms and I don't think it makes difference.

This is due to there not being the partitive case in English.
What do you mean by "partitive case"?
Also, if you don't mind,
2. Why are they both acceptable?
If I have money, It is likely that I will be using it to lend it to my friend.
If I have money, I will be using it to lend it to my friend.
To me, 'is likely' denotes present time, whereas 'will' denotes future time; and I feel in order to form a correct first conditional, one should use a future tense in the main clause.
3. Why is it wrong?
If you have money, can you lend me it?
Looks the same as:
If you have money, can you lend me the money?
