The lowercase g looks like the way that I write it, except I didn't design the font in the image…

Text says "play q&a games"

This is the font for the "Bowser's Inside Story" part of the logo.

Still need help with this one

It appears to be either Tahoma or Verdana

Serifs at the top of letters, the H, M, N, and R descend below the baseline.

It appears to be LilyUPC, but widened

I cannot find a good link to the font, but you can get it by clicking Download fonts for all supported languages in font settings in Windows Settings (Personalization > Fonts)

That depends on the license of the font. If it has a No Derivatives restriction, then editing is not allowed without permission from the font creator. (well, if it is edited, you may not distribute the modified font).
