I finally screencaped and analyzed the credits. I don't know that you can see it very well. It looks like Raf is voiced by Lisa Adams. According to the IMDB she voiced May in Pokémon. Angel's Friends is not listed. Although the character sounds more like Bloom who is voiced by Liza Jacqueline. I can't really make out the name of URIE's VA. I can't make out the next character's name, but she is voiced by Lisa Ortiz. Like I mentioned before her voice is very distinctive. It looks like Sweet is also voiced by Lisa Adams. I can't make out the next name. Gas is voiced by Dan Green. I thought I heard his voice in that show. I can't make out the name after that. The professor is voiced by Mike Pollock.
It was really hard to make out the names because the channel is a subchannel and the compression rate is 2Mbps. According to RabbitEars.Info. Also the DVD I recorded it on was on LP mode.
Here are some screencaps for you to enjoy. These are from the opening credits/theme song.
Here are 2 other caps and a picture I found. Here is a link to some character profiles.
