In[1]:=
funcs = {f1,f2,f3,f4};
vals = {val1,val2,val3,val4};
Map[#[[1]][#[[2]]]&,Transpose[{funcs,vals}]]
Out[1]=
{f1[val1],f2[val2],f3[val3],f4[val4]}
So, the "one liner" above will, I think, do what you want, but it's
hardly eloquent, and far from transparant. I suspect that Mma has a
cleaner build in function that, used appropriately, will do a cleaner job
here. I await the wisdom of the group.
