Tang Band W5-1138SM 5-1/4" Neodymium Subwoofer
I am building a subwoofer tube. I have .2cbft to work with and some calculations have shown a 1" port length of ~ 6.5" long to get a frequency of 38hz. Does that sound correct? I want between 35-40hz and have limited available space. Cheers.
Yes this volume and port size will work. There might be some port noise present at higher volume levels but if the subwoofer is placed in a hidden area it may not be audible.

I need to replace a big box 12 Paradigm subwoofer in a room that is 12x18 feet. Can I run 4 of these in series parallel. What would a ported box look like size wise. I have a maximum set of dimensions which are 7x14x20.
A box with those dimensions will work if you can put an elbow in the port. A 4" diameter, 20" long port is recommended for a tuning frequency of 39 Hz.

I wanted to make a small subwoofer to fill out the low end for my f150. I would like to use a 6" pvc pipe but I would like suggestions on what length would be best to get the most low end bass. Not sure if I want to go sealed or vented. Thanks!
A sealed enclosure will only need a 7-1/2" length of pipe for the proper volume, but this yields an F3 of about 70 Hz. A vented enclosure would need to be 24" long with a 2" diameter, 15" long port for a tuning frequency of 38 Hz.

Is this a freeair subwoofer
This will work relatively well free air but it will have limited extension below about 50 Hz.

I am a newbie to building speakers but i have a pioneer 12" shallow sub box .5 cu/ft and a 12" dayton passive radiator and was considering using this 5 1/4 " sub driver in that same shallow sub box with the 12 inch passive radiator. possible?
This combination would work relatively well in that volume. I would recommend adding 200 grams to the passive radiator for a tuning frequency of 38 Hz.

I am thinking of using this little sub in a DIY sound bar with 2 Tang Band W4-1337SDF powered by Dayton MCA2250E 2.1 25x2 and 1x50. Questions what is the best direction to fire the sub i.e. forward, down, etc... @ .36' what port length and diameter
The orientation of the woofer won't really make any difference in this case. If you plan on having it crossed above about 150 Hz to the other speakers you might want to front fire it, but any lower and it won't matter. I would recommend a 2" diameter port that is 10" long for a tuning frequency of 45 Hz.
