Can these miter uhmw sheets?

Yes they can. being a "Large" bit, you should slow down the router speed, this will also help prevent melting.

How is the quality of the brand MNA?

Ok. This is a cheaper brand so quality is a bit lower but for small infrequent projects their bit sets are great!

Can it be used for 22.5 angles? I want to do an octagon with pieces locking into each other.

No, this is only for a 45 degree angle. That would require a different bit altogether.
