Yuki,
The Friday condition is
x=DayOfWeek()==5;
It is a binary condition. x is 1 on Fridays and 0 for the rest days.
When the month changes, the
Month()!=Ref(Month(),-1)
is true.
We have 5 possible Fridays in a month
1st Yellow
2nd Green
3rd Red
4th blue and
5th Black
A grey candle marks Fridays in general.
The rest are

Plot(C,"",IIf(x,colorLightGrey,colorBlack),64);
z1=x*(Sum(x,1+BarsSince(Month()!=Ref(Month(),-1)))==1);//1st trading 
Friday
PlotShapes(shapeUpTriangle*z1,colorYellow);
z2=x*(Sum(x,1+BarsSince(Month()!=Ref(Month(),-1)))==2);//2nd
PlotShapes(shapeUpTriangle*z2,colorGreen);
z3=x*(Sum(x,1+BarsSince(Month()!=Ref(Month(),-1)))==3);//3rd
PlotShapes(shapeUpTriangle*z3,colorRed);
z4=x*(Sum(x,1+BarsSince(Month()!=Ref(Month(),-1)))==4);//4th
PlotShapes(shapeUpTriangle*z4,colorBlue);
z5=x*(Sum(x,1+BarsSince(Month()!=Ref(Month(),-1)))==5);//5th
PlotShapes(shapeUpTriangle*z5,colorBlack);

For a less academic approach, the 2nd Fridays are found by the F2 
condition
x=DayOfWeek()==5;y=Month();
z2=ValueWhen(x,y,2);
F2=z2!=Ref(z2,-1);
Plot(C,"C",IIf(F2,colorLightGrey,colorBlack),64);
PlotShapes(shapeUpTriangle*F2,colorGreen);
