Words order: 我们两个是好朋友 I faced sentence with word order that is different from expected "我们两个是好朋友" instead of "我们是两个好朋友". Does it have some different meaning?
Not much of a different depends on the question asked if this is an answer:  

我们两个是好朋友 - Us two are good friends  

我们是两个好朋友 - We are two good friends
