敬个礼 - to salute 握 握 手 - and shake hands (a form of polite gesture when meeting people) http://www.mamalisa.com/?t=es&p=2540&c=11

敬个礼 means to salute and 握握手 means to shake hands. It's a sentence from a children's song called "找朋友". I think this sentence means two children make some friendly gesture when they meet each other and then become friends. It doesn't mean the literal meaning.

这是一首儿歌，描述的是小朋友见面的时候可以敬个礼，握握手，你是我的好朋友。

你是我的好朋友!

敬个礼：salute each other 握握手：shake hand with each other this sentence is from a children's song. when children meet each other, they salute and shake hand with each other,and then they become good friends.
