By establishing second main theorems for holomorphic curves from angular domains \(\Omega_{\alpha,\beta}=\{\alpha<\arg z<\beta\}\) into the projective space \(\mathbb{P}^n(\mathbb{C})\) intersecting families of slowly moving hyperplanes with truncated counting functions, we study the growth of holomorphic curves from \(\mathbb{C}\) into \(\mathbb{P}^n(\mathbb{C})\) with radially distributed slowly moving hyperplanes. On the other hand, by establishing some second main theorems on \( {\overline{\Omega}}_{\alpha,\beta}\) with Tsuji characteristic function, we give some uniqueness theorems for holomorphic curves from \({\overline{\Omega}}_{\alpha,\beta}\) into \(\mathbb{P}^n(\mathbb{C})\) sharing few slowly moving hyperplanes.
