For once, I did not buy another orchid! It was given to me!

What do you guys think?
It's a mini onc. Carnival Costume.
It looks like it's trying to escape it's pot.
Are all those aerial roots normal, or a sign that I should repot?
Pic. #3 - is that a keiki?
Pic. #4 - is this a spike forming, or a new leaf? Looks like a leafy mitten.
Pic. #5 - sad looking pbulbs that look questionable. The roots are healthy, but the bulb is shriveling and the leaves are leathery and yellowing- with black spots.
get rid of it?
In any case, I'm super excited! I think she's lovely, and she has one completely unbloomed spike.
