Frost warning, will my plants survive

Hey I planted all my plants outside last week since I thought we wouldnt be getting anymore frosts in my area but according to the weather network there is a frost warning in effect in my area. All my plants are about 1 ' tall. I am unable to cover or shelter them since im not in the area til next week. Should I expect to go back to see a dead crop or can plants tolerate a frost or 2.
 
My plants survived the frost but didn't survive the animals in the area... 7 out of my 15 girls gone. Very upset but I am not going to let it discourage me.

Luckily I still have 4 White Widow indoors and not planning on putting them out til July.
