Hi,

Good to hear that you are able to create the ppa.
Answers to your questions are inline:

There is no dependency on other ppa. For gdal-grass, you just need to 
build grass (and wait for it to be published) before building 
libgdal-grass in the same ppa.

You can build your own versions on your ppa, there is no dependency to 
UbuntuGIS.

You will need to build ITK5 and then make the proper adjustments to the 
OTB package.
As far as I know, OTB does not yet support ITK5 and it was dropped from 
Debian Unstable for that reason.

You will need to create a new debian package, good starting point:
https://debian-gis-team.pages.debian.net/policy/packaging.html
