That's a big problem. Not great, but tolerable. Your second table is very problematic, your p-value in the ANOVA table, that is, sig, for 0.170 this number is greater than 0.1, can not think that your regression equation is meaningful ah. Then look at the third table, this is a direct play bad rhythm ah have not? The p-value in your coefficient table is sig, and four of the six items are much larger than 0.1, which makes no sense at all. so, your model is a big failure.

Suggest a different model. The model is a stepwise regression, or forward method, backward method, anyway, there are so many kinds of regression. Also try trend surface analysis.
