im no expert. but the pied is clearly a pied. and i also see a bumble bee and something quite similar to a bumble bee but still different. thats probarbly the fire spider, i dont know that combo very well but its definitively more than just a spider.
the last one could very well be a pastel.
but i think others need to chime in on the fire spider and the pastel.
i have to say its a nice little collection :)
