Should I protect my palms in these temperatures?

Apparently we will go down to -3 (26F) on Friday without any rain, so I wont be worried about a wet freeze, should I still protect my palms in these temps?

Palms I have outside: Chamaedorea Seifrizii, Wodyetia Bifurcata and Areca Catechu.

I think Wodyetia Bifurcata and Areca Catechu will 100% need protection at 26f. My chamedorea Seifrizii survived 28f this week here unprotected but it was under canopy, so it depends if it's in a microclimate or not.

I think Wodyetia bifurcata and Areca catechu will be 100% DEAD without any protection...

28F with frost killed 9 out of 9 Foxtails in the open in my yard.  The 3 on the SW side were protected from frost by my neighbor's 70' tall oaks.  They took only minor burn and a bit of yellowing.  I'd say yes, they need protection.  My recollection is that Areca Catechu dies under 30F and may take severe damage in the lower 30s?

A. Catechu is in a protected spot with a lot of light. But Foxtail isn't. I will cover them with a warm material tomorrow morning.

Absolutely. Areca catechu is a zone 11 palm. You need to cover it and supply supplemental heat. Foxtail may be slightly hardier but 26F will fry it. Your “warm material” is useless at that temp unless you add heat. No spot is “protected” at temps in mid-20s. You need to get to work.
