I am suppose to make a flow chart... would i use HCL to separate Bi3+ and Ag+ from Ni2+?

Ag is in group I so it can be pptd as AgCl without disturbing Bi or Ni.
Bi is in group II, so it can be pptd as Bi2S3 with H2S from a slightly acid solution. See your qual scheme.
Ni is in group III and will be left in solution after Ag and Bi have been removed. If you wish to collect the Ni, it can be pptd as NiS from a basic solution of H2S.
