I think the folic acid is okay, as long as you use B12 with it.
There is some controversy about folic acid vs methylfolate now.
The theory is that folic acid may compete with the methylfolate at the blood brain barrier. So the B-right has methylfolate in it, and if you give extra, it might be best to stick to that form.
Folic acid is not active in the body and has to be activated to the methyl form.

The timing is not so important. The oils go best with food, and the B12 should be done on an empty stomach. Those are the only major issues to watch for.

Carlson's is good. We used it for our son for his ADHD supplementation.

I have found that taking my Krill oil at night, seems to work better for me than in the daytime. I seem to sleep better and have more dreaming. So taking some of the fish oil at night may work the same way. Krill does not reflux but the fish oil might, so taking it at supper and remaining upright after dinner is best.
