If the strain is sativa or sativa dominate it can take the heat no problem if the light isn't too close. Indica may not like the heat, but will be okay with good air circulation. Sixty degrees is okay, but you don't want it getting too cold if possible.

Keep the humidity down and blo the shit out of them with fans. Stakes are imperative or string or SCROG. Silica supplements would be advisable for long term heat. Running that temp for 8 weeks is not advisable. Keep it below two, if possible, otherwise you will run into problems.

Not good. Try to keep 81 tops, and 86 max. But 91 is definitely doable, vastly depending on your rh. During night too.
I had a run years ago where my temps were 82f day 54-56f night. Don't recall rh though. But my plants flourished and grow great, not as good as ideal conditions. But passable

Some horrible advise on this thread. When your temps are high, the last thing you wanna do is lower your humidity. You want to raise it so your plants don't transpire as much water to keep them cool. Look up VPD chart. You also want to lower your nutrient strength because your plants are going to want more water than food with the higher temps.
