We present our ELODIE radial-velocity measurements of HD 74156 and 14 Her (HD 145675). These stars exhibit low-amplitude radial-velocity variations induced by the presence of low-mass companions. The radial-velocity data of HD 74156 reveal the presence of two planetary companions: a 1. 86 MJup planet on a 51. 64--d orbit and a 6. 2 MJup planet on a long-period (5. 5 yr) orbit. Both orbits are fairly eccentric (e=0. 64 and 0. 58). The 4. 7MJup companion to HD 145675 has a long period (4. 9 yr) and a moderately eccentric orbit (e=0. 34). We detect an additional linear radial-velocity trend superimposed to the periodic signal for this star. We also compute updated orbital solutions for HD 209458 and 51 Peg (HD 217014). Finally, we present our ELODIE radial-velocity data and orbital solutions for 5 stars known to host planetary companions: Ups And (HD 9826), 55 Cnc (HD 75732), 47 UMa (HD 95128), 70Vir (HD 117176) and HD 187123. We confirm the previously published orbital solutions for Ups And, 70 Vir and HD 187123. Our data are not sufficient for fully confirming the orbital solutions for 55 Cnc and 47UMa.
