I'm having a hard time visualizing how they should be laid out. Something that comes to mind though, is that the blueberries are going to need acidic soil, so you will want to keep them together and not inter planted in amongst the rest. It might help to see the space (my camera is broken - so I know that pics are always easy to share). A question thought, why are you thinking about getting rid of the forsythia (I am biased, since I enjoy watching birds and miss cardinals)? Sorry not to be more help.

I can't tell what the existing brick is doing--do you want to install rocks there? I can't help with that. But on the boxwoods--I thinks it would look nice to continue them under the window to the right. Remember that there are several different species and cultivars of boxwoods. Take a piece from yours with you to see if you can find matching ones. Do you know what the deciduous shrubs under the windows are? Just in case they are worth keeping? If you can continue the boxwoods and put your burning bushes in front of them, then I would want a low evergreen border. I agree on taking out the junipers. Where are you? location and zone will help with suggestions.

I am wondering why so many of your plants died? Too much water, not enough water, planted when too hot and not shaded, were the plants in poor condition when planted, etc? I suggest you figure that out first before spending money on more plants. Do you like the look of fewer plants surrounded by mulch or a bed full of plants with little mulch showing? I think the hosta grouping adds flow to the bed. You might want to move them elsewhere but the layout is good. Eventually the one nearest the ninebark will need to be moved forward. IMO plants circling trees and shrubs are not as interesting. Choose plants that are different heights and some with different leaf textures. What are your favorite colors of blooms? Do you want plants that flower different times of the year, spring, summer, fall? Do you want mostly nonflowering perennials/ shrubs and some flowering annuals that add interest? Or mostly perennials/ shrubs, flowering or not? I suggest that before buying more plants you walk and drive around your area to see what grows well for others and which plants you like. Maybe this plant from someone's bed and that plant from another place. Visit nurseries to see what is offered? Then make a list of the plants you like and check their growth requirements and if they would work with your light and space limitations. Look at photos of gardens to get other ideas. I know one wants the space landscaped right now but taking the time to answer the above questions and to discover what you like will result in you being more satisfied with the resulting landscape. Or, hire a landscaper whose work you admire.

No, I am still here. Thanks guys for your all suggestions replies. To be honest I am more on the side of Photinia than on Camelia. It is hard to say, they have never saw any blooming on those trees and leaves do look red . But in any case I think they will keep those trees for now, they will trim but that bush (as kiminpl called blob) they probably will remove it and plant small tree as Yardvaark(9A) mentioned. Yardvaark(9A) Thanks for your design and suggestions. We like the idea of multi-trunk tree in front of the blank wall. As biondanonima said it is weird layout. The walkway leads to the driveway/garage that's correct. So thats why there are no reason for them to walk directly out the door and out to the street. And that's why they don't need walkway from the sidewalk directly to the front door. So the idea is to make this entrance more closed from the public. To plant plants in order cover the ugly layout and huge wall, make some privacy. Because the entrance is facing the main road and it is a corner house. There are used to be two huge oak trees in front of the house. When they moved in they had to cut it because they were dead. Thats why that wall look very weird. Here is the picture from 2008. Here is the picture from 2016, you still can see sign on the grass from oak trees I probably should have mention that this is corner house and facing main road. But the real entrance leads from driveway. One more picture:
