I just loaned to 5 people in Lebanon,who had just hours to go for their funding to be completed,
as I was only allowed to loan $25 each,it appears they will not achieve full funding in time.
My question is what happens to the fund s they have raised so far?? do they receive the incomplete funding?

I'm not sure exactly what you meant about only being
allowed to loan $25 each. Kiva would allow you to loan as much as you like. On the lend page there is only the orange Lend $25 button, but if you go to the individual loan page there is also a drop down button under the text "Select amount to lend" where you can choose from a limited range of values. Also, once the loan is in your basket there is a drop down button where you can choose to lend anything from $25 all the way up to the total amount needed.
The answer to your question though is that they do not receive partial funding. If they don't reach the full amount your $25 loans will be refunded to you so you can lend to another borrower. I hope that helps.
