Level of creatinine high = 5 and crp= 77 is that means insuffisance reinale?

Yes. Elevated creatinine level could mean renal insufficiency, with or without crp.
Yes and no. Creatinine = 5 suggests fairly advanced kidney insufficiency. CRP is a marker or measure of inflammation (many things including insuffisance reinale can cause that); a level of 77 is high suggesting active inflammation.
