What is the largest size eyepiece that will fit in the extender tube?

It will work great with most eyepieces, for example, 1.25" plossl eyepieces and 1.25" 66-degree ultra wide angle eyepieces and more. The inside diameters of stationary barrel and main Barrel are 3.22CM and 3.81CM, so please make sure that the largest diameter of your eyepiece less than 3.81CM and eyepiece barrel less than 3.22CM.

Will this fit a nikon d3400 t-ring

It fits my standard Nikon DLSR T-Ring.

I already have a T-ring adaptor for my Nikon D5100. will the threading of this piece work with my t-ring?

Your existing T-ring should work fine.

Will i be able to connect this to 55mm panasonic lumix fz80 camera?

No. You need a camera with interchangeable lenses like an SLR or mirrorless plus a T-Ring specific for that camera.
