You're in luck! Matlab's documentation contains a page that specifically explains the process of sharing variables between apps.
Although that page comprehensively explains the process, here's an answer that shows a step-by-step process of declaring app properties. You can use "public" properties.

i want to access the updated value of "name" in GUI4. "name" gets changed in GUI2 via a text field.

The line below with the leftward arrow is accessing the name propery of GUI2!
If this function is within GUI4, then use app.name since the app content pertains to GUI4.
%my second app called GUI4.mlapp
function startupFcn(app)
app2handle = GUI2
app2handle.name % <------------------------
end
