Hi Rino,
Can you please rephrase the questions. Its a little hard to understand what you're asking.
Are you asking if it's okay in an Ad Group to include multiples of the same keyword but with different match types? If so, YES!
Now there are many different philosophies regarding how to structure your campaigns. Some prefer to separate their Ad Groups by match type, other by individual keyword and there are many more ways to structure your campaign.
Personally I like to structure by Ad Groups by keyword or similar keywords so as to make sure that my Ads contain the keyword in their copy but everyone has their own opinion.
I hope this answered your question!
