As a general rule avoid Do and For loops and just operate on Lists or
Map (/@) onto lists.
g /@ {f1[r,theta,phi], f2[r,theta,phi], f3[r,theta,phi]}
{g[f1[r, theta, phi]], g[f2[r, theta, phi]], g[f3[r, theta, phi]]}
This can be written more compactly as
g /@ (#[r,theta,phi]& /@ {f1,f2,f3})
{g[f1[r, theta, phi]], g[f2[r, theta, phi]], g[f3[r, theta, phi]]}
