[College Genetics] 5 point cross; What is the phenotypic class of 5 point cross?

I got the answer for those who need to figure out 4 or 5 point cross: Assuming that wild type allele of ru1, h1, st1, ry506 & e4 is Ru, H, St, Ry & E respectively.

4 point cross:

Gametes from heterozygous female \rightarrow HStRyE, h1st1ry506e4 (Parental);

Hst1ry506e4, h1StRyE (Single cross-over between H & others);

HStry506e4, h1st1RyE (Single cross-over between St & Ry);

HStRye4, h1st1ry506E (Single cross-over between E & others);

Hst1RyE, h1Stry506e4 (Double cross-over between H & Ry);

Hst1ry506E, h1StRye4 (Double cross-over between H & E);

HStry506E, h1st1Rye4 (Double cross-over between St & E);

Hst1Rye4, h1Stry506E (Triple cross-over between H & E);

Gamete from homozygous male \rightarrow h1st1ry506e4

The cross between a heterozygous female drosophila with homozygous male drosophila for h1 (hairless), st1 (scarlet), ry506 (rosy) & e4 (ebony) is shown below Punnett square.
