Is the RAM upgradeable?

No. The memory is soldered to the board, so the 8 GB fitted at purchase is what you get.

Does it come with a pen?

The touchscreen supports an active pen, but whether one is included depends on the bundle. Check the box contents before buying.

Only lightly. Integrated Intel graphics handle older and casual titles, not modern 3D games.

It is a glossy touch panel, so reflections are noticeable in bright light. It is fine indoors.

Yes, the M.2 SSD is user-replaceable, which is the main way to add storage later.
