This is a good question and deserves some clarification on a number of issues.
First of all, we must understand what is meant when we classify Surahs as Makee or Madanee. The common definition is by
date of revelation. Hence, Surahs before the Hijrah are considered Makee while those after are considered madanee. It is a chronological seperation, NOT a geographical seperation.
So those verses revealed at the conquest of Makkah for example, are Madanee verses, even though they were revealed in Makkah.
Secondly, a
Surah is classified as Makee or Madanee, depending on its first verses. So a Surah that is mostly Madanee but starts with only a few Makee verses, is still considered Makee.
Now I would just like to outline characteristics of Makee and Madanee surahs before moving on to your question.
Makke surahs
1. Every surah that has the oath "kalaa" (nay!) is makee.
2. All surahs beginning with the disjointed letters (al-muqatta'aat) are makkee. eg. Ha-meem, Alif-laam-meem, etc.
The only exceptions to this are Al-Baqaqarah and Al-Imran.
3. All surahs which have a verse of prostration (sajdah at-tilawah) are makee.
4. All surahs which memntion the story of previous prophets are Makee, with the exception of Al-Baqarah
5. The verses in Makee surahs are usually short with frequent oaths.
Madanee surahs
1. Every verse that mentions a punishment for a crime (hudood) is Madanee
2. Every surah that mentions the hypocrites in madanee, except Surah Al-Ankabut
3. Every surah that addresses the Jews and Christians is Madanee
4. Every surah that mentions jihaad is Madanee
5. generally, Madanee verses are longer than Makee.
Coming to your question, there are many categories of Qur'anic surahs, and one of them is Madanee surahs with Makee verses. An example is Suratul Anfaal, which is Madanee except for verse 64, which is Makee.
For more info, I recommend reading what has been written by Shaykh an-Naysabooree (d. 406 AH), in az-Zarkashee, v.1, p. 192.
