I paid off my 5 credit cards, should i close them?

I paid off all 5 of my credit cards, I would like to cancel 3 of the highest APR and keep the 2 with the lowest APR. I got these cards when my w as poor and paid them all on time but the maintenance fees are expensive to keep open. How will this affect my credit if I close 3 of them? Hopefully it would not lower my score to have less open lines of credit. Thanks
