Maayos anG kuwarto ko

Magulo anG kuwarto ko, pakilinis *
or
Linisin n'yo *

* - though these words are correct, they would come across as bossy and impolite.  We usually add "nga po" after them to make them sound as polite requests -> pakilinis nga po; linisin n'yo nga po. If you are addressing a younger person, you may say, "pakilinis mo nga" or "linisin mo nga", but you should say it gently so as not to sound offensive.  

bobo ka - this means, "you're stupid". Watch out when you use it as it may get you in trouble.  

Mailinis sa London -> Malinis sa London

Madumi sa ikwater -  Did you mean "squatter" (iskwater)?

The rest are OK.
