I think mine is 6th Generation, because I have the Red iPod Touch and I notice in parenthesis at the bottom:
iPod touch (6th generation) is available in five colors, as well as a (PRODUCT)RED version.
I believe the Product Red version was also available in the 5th gen models.
However, as you have the Product Red version, to correctly identify between a 5th and 6th gen Touch, look on the back case. If the back has a pop-out button (known as the Lanyard Loop) in the lower left corner, it's a 5th gen model:
(I believe the 16GB iPod Touch in 5th gen does not have this button, but the 16Gb was not available in Product Red.)
The highest version of iOS that the 5th gen Touch can run is iOS 9.3.5.
The back of the 6th gen Touch looks like the one below:
Note that the 6th gen Touch does not have the pop-out button. The highest version of iOS that the 6th gen Touch can run is (at the time of writing) iOS 12.4.4. My understanding is that it cannot run iOS 13.
So to summarise, an app that requires iOS 9.4 or higher cannot be used on the 5th gen Touch.
