Perhaps the reason you've not got a response sooner is that these All-in-One unrelated question threads don't do well here. You would do MUCH better if you post a thread for each problem especially since these are unrelated.

But, two answer some partition-related questions:
1) GRUB does not have to be installed to a Primary partition; it will work fine in a Logical partition.
2) Windows OS needs to be installed to a Primary partition, and to make things easier, if you're installing both MS Windows and Ubuntu, each to their own partitions, install MS Windows first.
3) Using traditional partitioning. 4 Primary (or 3 Primary and one Extended) are all the partitions allowed. If you are using something like GPT or UEFI BIOS, I am unfamiliar with those and can not answer your questions.
4) With Ubuntu, you really only NEED two partitions: one for the OS, another for SWAP.
5) MBRs don't get copied as they are unique to each physical drive -- and outside the partition space.

Please post new threads for your other questions. thanks
