What are these anime's called?

• These use to be awesome animes that came on Saturday Anime on SciFi and I barely remember whats going on but if you know or think you know please help lol 1) it was a "newer" looking anime in space where there was a alien killing the passagers on board. There was also a convict on the space ship thats all I really remember 2) older looking anime where the earth was going to be destroyed basically by the human race and only a few of the population could go on to spaceships to head to "Earth" to start new life and the main charater and his love affair were left behind at the end (very sad) 3) Guy with a wooden stick who fights demons looks like it was made in the 80's and there was a kid on roller blades. 4) girls in tanks and i think they were police officers fighting a guy with glasses on. I'm sorry I can't remember much about each anime but if you know any of them please help me they have been haunting me for a while number 1 the most thanks My top 5 anime series 1)Outlaw Star 2)Trigun 3)YuYu Hakasho 4)Death Note 5)Lodoss War
