I have an meeting in Friday. It will starts at 8am.
I have a meeting on Friday. It will start at 8am. 

Suggestions: 

1. Always use "a" instead of "an" before a word starting with the letter "m"
2. Use "on" instead of "in" to indicate the day of the meeting
3. Use "start" instead of "starts" as the verb is in the future tense, not the present tense.
