What do you do if your best friend lied about your other best friend lying but you still like both friends so you don't want to ditch either one?

Get off it! If you're not able to confront these "best friends"of yours, drop them already. All relationships are built on honest interchanges. Otherwise you're just being used. Read Melody Beattie's "Choices: Taking Control of Your Life and Making it Better."if your best friend is lying to you than their not your best friend . if they were your real best friend then they would not lie to you.they would tell you the truth so im not telling you to go and tell them their not you friend any more and to stay out of you life.but talk to them and try to make them talk to you.
