What is the maximum possible number of streets any one of which could be the one the crew cleaned on Friday afternoon?

we know this : 8th has to be Monday afternoon, 4th street is tuesday morning, no spots on Wednesday afternoon and Friday morning. 7th street is thursday afternoon. it is told that 2,5,8 are afternoon. meaning 6th street must come in Wednesday morning or Thursday morning and can not fit Friday afternoon since that slot has to be reserved for one of the other numbers. Leaving us with 1,2,3,5 (4 numbers)
