Your main problem here is a lack of data.  A "Breusch-Pagan test is nonsignificant (Chi-square(4) = 1.77291, p= 0.777434)" does not reject the null of heteroskedasticity.   With your short series, however, the test has very low power.  Check what you are doing here. 

Without some knowledge of the economic model that you are trying to estimate and your data, it is not possible to advise you.  Perhaps you should check your application of the Breusch Pagan test to your pooled regression if that is what you have done.

For my panel data (all continuous variables; 1 DV, 4 IVs; 8 time points for each of the 5 companies), the Breusch-Pagan test is nonsignificant (Chi-square(4) = 1.77291, p= 0.777434) implying that both Random effects model and fixed effect model are not appropriate.  I used the OLS regression with heteroscedasticy problem.  Any suggestions on how to remedy this?

Appreciate your help.
