1, 2) Yes. You can use this code to change the title style:
B4X:
Private Sub Application_Start (nav As NavigationController)
   SetNavigationBarTitleStyle(Colors.Red, Font.CreateNewBold(20))
   Dim nav As NavigationController
   nav.Initialize("nav")
   App.KeyController = nav
   NavControl = nav
   Page1.Initialize("Page1")
   NavControl.ShowPage(Page1)
   Page1.RootPanel.LoadLayout("1")
End Sub

Sub SetNavigationBarTitleStyle(Color As Int, Fnt As Font)
   Dim attributes As NativeObject
   attributes = CreateMap("NSFont": Fnt, "NSColor": attributes.ColorToUIColor(Color))
   Dim no As NativeObject
   no.Initialize("UINavigationBar").RunMethod("appearance", Null) _
     .RunMethod("setTitleTextAttributes:", Array(attributes.RunMethod("ToDictionary", Null)))
End Sub
Note that you need to create a new NavigationController and set it as the KeyController (see the code above).

3) The image will show as a single color image based on the non-transparent pixels.

It does work. I just tested it.
Make sure that you set the property to the current page (the top most page).

You can set the navigation bar tintColor property to change the color of all the bar buttons:
B4X:
Sub SetNavigationBarTintColor(clr As Int)
   Dim no As NativeObject = NavControl
   no.GetField("navigationBar").SetField("tintColor", no.ColorToUIColor(clr))
End Sub

I would change font and size to text of prompt, i'm try to replace

setTitleTextAttributes with setPromptTextAttributes, but doen't work.

other to show me the final solution, can you show me how to find native parameters?

i hope the next version will have these parameters in basic or design mode :)
