Christopher,

Use ReplaceAll (/.) as follows:

In[1]:=
{a1, a2, a3, a4, a5} /. {a1 -> 0.00400772472374540367,
a2 -> -1.90417580406264459*10^-6,
a3 -> 499088.922439139537, a4 -> 1.31534993678125777*10^-9,
a5 -> 7728.37550019371821}

Out[1]=
{0.00400772472374540367,
-1.90417580406264459*10^-6,
499088.922439139537,
1.31534993678125777*10^-9,
7728.37550019371821}
