Problem With large prints on Lulzbot Taz6
Unluckily - for as much information on your settings you share - it is very difficult to diagnose the problem without knowing how the print failed.  Did a piece become dislodged? Did the nozzle caught onto a printed piece? Did the head began extrude in mid air? ...?

However this are my guesses:


From your temp settings it looks like you are printing ABS.  If this is the case, have you placed your printer in an enclosure?  With ABS, It is very very difficult (if not impossible) to print anything above "small", without an enclosure.
Printing 100% infill is normally a bad idea.  If you are doing it for strength, then you should know that the strength gains are progressively smaller on anything above 60%.  100% infill also means that unless your extrusion is perfectly calibrated (which I suspect it may not be the case, given that your setting is the default 100%) any amount of overextrusion will likely let the nozzle "catch".  Finally, 100% extrusion also increases the warping forces on the piece considerably.
Printing a cylinder "laying down" is hard: you basically have zero adhesion to the printing bed and must rely on the support material to stabilise your part.  But the support material is designed not to bond securely to the main piece and it will be unable to counterbalance any "curling up" that your part may experience due to thermal contraction.


So, my suggestions:


Use an enclosure (even a simple cardboard box on top of the printer will do for a starter).  Definitively use an enclosure if you are printing with ABS
Calibrate your extruder.  Here is a handy guide. :)
Reduce your infill density to something between 60% and 97%.
Print your parts one at a time, start from the vertical cylinder and - when you have got that right - try the horizontal one.
If you must print one of the two horizontal...


Increase the support density considerably, and diminish the Z-distance between support and print to the bare minimum.  If your edition of cura has that setting, use support interfaces at full density.
Alternatively eliminate the headache completely and print two semi-cylinders instead (cut the cylinder in half along its length, printing them with the "cut" as their base) and glue them together afterwards.  If you are using ABS you can "weld" them with acetone instead.
