I agree with Lisa: some of these, but not all of them, appear to be examples of AAVE (African-American Vernacular English) which most working-class and middle-class African-Americans speak as a native dialect of English, especially in urban areas. Some of the others are slang.
It will be interesting to see how my opinions on these compare to Lisa's.
1. "They seen animals" = "they have seen animals". Dropping of the auxiliary "have" in perfect tenses is common in several colloquial varieties of US English, including speakers of AAVE. I think that "we made stages" means "we performed on stages".
2. "freestyle" is doing something by making it up as you go rather than fitting within a particular way of doing it; for example, dancing freestyle rather than dancing a particular type of dance such as waltz, two-step, ballet, tap, and so on.
3. "the 80%" is a short way to say "the 80% of people".
4. A "set up" is a specific arrangement of a group of things or of personal circumstances. In this case I think he refers to where and how he lives (home, work, family & friends, religious community, whatever).
5. "turn off the 110" refers to traveling a major road in the city of Los Angeles, which is a limited-access highway that is identified as Interstate Route 110 and also identified as California State Route 110. This highway runs south to north through the middle of Los Angeles. Most people in Los Angeles refer to that road as "the 110". "Turn off the 110" means "take an exit off of Route 110".
6. "wheels" is slang for "car" or "automobile". Here "they got your world on wheels" means that everyone goes from place to place by private cars.
7. "off the 10" refers to a different major road, Interstate Route 10, which runs between the coast of the Pacific Ocean in Los Angeles to the coast of the Atlantic Ocean in Jacksonville, Florida. In Los Angeles this highway is an important east-west highway in the same way that Interstate 110 is an important north-south highway.
