Along many alternatives you can try:

In[7]:=
lst = {{a1, a2, a3}, {b1, b2, b3}, {c1, c2, c3}}
Out[7]=
{{a1, a2, a3}, {b1, b2, b3}, {c1, c2, c3}}

In[8]:=
lstnew = (Insert[#1, e, -1] & ) /@ lst
Out[8]=
{{a1, a2, a3, e}, {b1, b2, b3, e}, {c1, c2, c3, e}}

In[9]:=
lstman = Apply[f, lstnew, {1}]
Out[9]=
{f[a1, a2, a3, e], f[b1, b2, b3, e], f[c1, c2, c3, e]}
