We present measurements of branching fractions and charge asymmetries for 
seven B-meson decays with an eta, eta' or omega meson in the final state.
The data sample corresponds to 89 million BBbar pairs produced from e+e- 
annihilation at the Upsilon(4S) resonance.  We measure the following
branching fractions in units of 10^{-6}:
B(etapi+)=5.3+/-1.0+/-0.3, B(etaK+)=3.4+/-0.8+/-0.2, B(etaK0)=2.9+/-1.0+/- 0.2 
(<5.2, 90% C.L.), B(eta'pi+=2.7+/-1.2+/-0.3 (<4.5, 90% C.L.),
B(omegapi+)=5.5+/-0.9+/-0.5, B(omegaKp)=4.8+/-0.8+/-0.4, and
B(omegaK0)=5.9+1.6-1.3+/-0.5.
The charge asymmetries are A_ch(etapi+)=-0.44+/-0.18+/-0.01, 
A_ch(etaK+)=-0.52+/-0.24+/-0.01, A_ch(omegapi+)=0.03+/-0.16+/-0.01 and
A_ch(omegaK+)=-0.09+/-0.17+/-0.01.
