Replaced 4x2tb drives with 4x 4 tb drives one by one while in raid 5, i expected the tr004 to recognize extra space on last replacement. not. so how?

RAID does not work like that. When you create an ARRAY, the configuration is written to a configuration file that is either stored on the drives/array or whatever software RAID file you are using. Even in Enterprise Storage, this is how it works. Swapping out to a larger drive will not increase your disk space. You would need to backup your data, then wipe and create a new ARRAY.

How large of a hd tb size is it compatible with?

I've got 4x WD Red Pro 20TB - WD201KFGX running in mine just had to upgrade the firmware to v1.2 (anything lower won't work). Just put in a single drive that's less than that size, plug into your machine, and run the "QNAP External Raid manager" utility to update the firmware (all on their support site).

can it connect directly to router without pc ?

I connected it to my PC first, formatted the 4-drives in raid 10 (NTFS) (using hardware switches, NOT software), created the folders I wanted in it, then connected it to my ASUS router which has inputs for USB storage devices, and all of my computers in the house can "see" the raid and use it for storage.

Can i set this up for raid 1 with 2 drives and jbod/single with the other 2 drives?

I think the question is implying can you set this unit up with two concurrent RAID volumes. A) A RAID 1 set with drives in slot 1 & 2 and concurrently B) a JBOD set with drives in slot 3 & 4. Based on DIP switches, no. It would need multiple sets of dip switches to accomplish this and it appears there is only one set of switches on the chassis. By software, it is a possibility if the management software is slick enough to support this. It would come down to what QNAP provided in the software management console. As I don't have one of these yet, I can't confirm.
