removing heat from system
If a reaction is exothermic, will the temperature always decrease? In not, what are the exceptions to this rule?

Yes, if a reaction is exothermic, it will always release energy and delta H will always be less than 0.

Exothermic reaction will always have a decrease in temperature as energy is being released. Once the temperature rises it will switch to endothermic as energy is being absorbed.

Exothermic means it releases heat so yes it will mean the temperature of the system decreases

Yeah, if a reaction is exothermic then temp will decrease. This is because the reaction is releasing heat (delta H is negative).

Re: removing heat from system
If Kc decreases with an increase in temperature, the reaction shifts to the left, making it an exothermic reaction. The Kc can also increase with a decrease in temperature, causing the reaction to shift to the right.
