So i remember the shows im am about to describe aired on PBS Sprout (now called Universal Kids).
Show 1: so it was about a bunch of anthropomorphic animals, with the main character being a zebra and the zebra having a sister, i also remember the house that the main character living in a house that was a sky blue color.
Show 2: it was a CGI or Live action show about a bunch of RC vehicles that... idk. I dont remember much.
Show 3: It was a show about a girl named Lilly who lived in a shack that i swear was like 5 meters wide, where she would use her imagination to go on adventures. Also, i remember the name of the show being starting with Lilly's Seaside... something.
1. Probably 64 Zoo Lane. I remember that airing on Sprout at some point around 2009ish? I'm positive there was a blue house. 2. Chuck and Friends? It aired on The Hub but maybe you're remembering wrong? It was themed around Tonka trucks so it's always a possibility.
