我的春节(的)计划 We usually omit either 的 to reduce redundancy. 

人人: everybody or people in general.

大家: everyone (specific). In this context, it refers to your family and friends. 

Good job!

我的春节的计划

As you are talking about your plan for the Chinese New Year, in a kind of formal way,  you would use: 我准备去（I am going to visit ... / 我计划去 I am planning to visit my girl friend's family.  However, in our daily life, you could also omit '准备/计划’, just use '去‘, people would still understand you mean 'you are going to visit' in the specific context.

Not sure what you meant - 奴朋友?   might just be a typo.   奴 means 'Slave'  :-) 

好朋友 good friend

女朋友 girl friend

大家都/ 我们都/每个人都穿红衣服：  We all wear red clothes/Everyone wears red clothes 

You did a good job, well done!
