Abstract: We construct quasi-particle bases of principal subspaces of standard modules L(\Lambda), where \Lambda = k_0 \Lambda_0 + k_j \Lambda_j, and \Lambda_j denotes the fundamental weight of affine Lie algebras of type B_l^{(1)}, C_l^{(1)}, F_4^{(1)}, or G_2^{(1)} of level one. From the given bases we find characters of principal subspaces.
