Any calculation of required memory of MDS nodes related to the OSD nodes
MDS memory usage depends on the amount of inodes it caches. By default
this is 100k, but I'm not sure how many (kilo)bytes it uses for a single
inode.
But be aware, CephFS is still under heavy development, so a lot can change!

total capacity?

Yes, not a problem. Be aware, the MDS can be memory hungry depending on
your active data set.
There is no golden rule for mixing daemons however.
CephFS is not stable yet however, keep that in mind!

That's not possible. There can only be one public network, so your idea
is not feasible.
