Can a use a ham radio in murs frequencies without a licence?

I'm looking for a radio I can use with and earpiece to talk to family and/or friends when riding trails, playing airsoft, fishing, ect. I can only find ham radios with earpieces and want to know if I just use murs frequencies would it be legal? Or would I still need a licence for that?

That and if I have a licence but I lend a radio to a friend who doesn't have one for a bit while playing airsoft or whatnot, what kinda legality situations are up with that?
