The red area on your track diagram is not a reverse loop, so don't worry about that. Peco Insulfrog turnouts are what's called a "Current routing" turnout. This means that as well as being a track switch, they are also set up to be electrical switches. Track power, if coming from the points end of the turnout, will only be passed on into the red area when the turnout is set for the red portion of the track. If the turnout is set for the other(non-red) track, the red track will not get power. Since you have an insulfrog turnout at each end of the red track, I would think that if either of those two turnouts were set for the red track, that would put power onto the red track,. If both were set for the red track, no harm would be done.
Looking again at your diagram, I see that you already have feeders to both the tracks coming out of each turnout, except one. Do you also have insulated rail joiners on both short frog rails of every turnout? If not, you should add them.
The one turnout that does not have feeders on both routes is the one at the top center of your diagram. One route does have feeders, but the other one would only get power through the turnout at the top , and a bit to the right. It would have to be set one way for power to get through to one of the routes of that top center turnout. I suggest adding one more pair of feeders to the track between those two turnouts.
You asked if all track be powered? Yes it can. Some people do not want the current routing feature. They bypass it by putting insulated rail joiners in both of the short pieces of rail coming out of the frog. Then they wire power feeders to the tracks beyond the frog as well as at the points end. in other words, power is fed into all three pieces of track coming out of the turnout. These feeders don't need to be attached directly to the turnout, just somewhere down each of the three tracks that lead to the turnout. If you do this to every insulfrog turnout, all the track on your layout will have constant power.
Do you have a multimeter? It's a very handy tool to have in these situations. It can tell you if the rails of the red track have power, or exactly where the power is not getting through to that track. It can also determine if you have a short circuit. The meter doesn't need to be a fancy, expensive one. Harbor freight tools www.harborfreight.com
sells basic meters from $5-$10 that are quite adequate for model railroad use. The photo below shows the $10 meter, I also have the $5 one, but don't have a photo of it available.
