RF design and layout [questions/feedback]

Hello! I'm designing a board with an LNA and filter and am looking for some feedback. I also have a question about ground filling the top layer; what distance should I observe from rf traces to ensure the same 50ohm impedance? Also, would a metal can help improve the performance of the board in a significant way?

Thanks again!

That does not look right at all.

What are you trying to achieve? What is your goal?
