Upgrading HD in NAS

I have a F5-221 TNAS ... I built the NAS with 4 3TB drive (2-Seagate Barracuda + 2 Toshiba DT01ACA series) as I had them sitting around not being used (all new). Since it is not the Ideal HD for a NAS .. I have procured a couple of SeaWolf Pro NAS drives... 4 TB each ... am planning on swapping out the Desktop Drives for the NAS drives ...
Currently the 4 are in a RAID-5 array .. can I simply pull one at a time and let the Array rebuild itself for each drive .. ? then gradually I replace all the drive over time ... or is there a better method .. ? Can the Array have different size drives and utilize all available disk or will I have unused disk because of the size differences?

Since RAID5 allows only one drive to be malfunctioned, you can pull out one HDD from the RAID5, insert the new one, and click " repair the RAID" to wait for the RAID rebuilding being finished. And repeat these process with the second new hard drive. Only one hard drive at one time.

are there any recommendations on which drives I should change first ... starting from Slot 1 ... I go the first two Barracuda the next two Toshiba... on this site I see it mentioned that the Barracuda drive are problematic ... since at the moment I only have two IronWolf drives should I be swapping out those two first?

That should be ok to replace the two Barracuda drives first. Please make sure that the storage size of the new drive is no less than the Barracuda one.

Since I am adding drives of a larger capacity ... do I need to follow any steps for the TNAS to see the additional disk space ... or will I need to replace all of the drives for that to occur? I had notice one post where someone needed to ssh into the device to use a LVG command to expand the storage... since the control panel did not display it ...

The usable space will be refreshed after RAID rebuilding is finished. The counting method of usable space for RAID5 is (n-1)*min, so if you have four HDDs with different size, the usable space will be 3*min.
