specify pom.xml in mvn command and mix goals of other project

I have multiple questions.

1. Can I specify the pom.xml in mvn command?

2. Can I mix the goals of another project while executing mvn command on current project ?

   Eg: mvn clean-otherproject comple-otherproject instal-otherproject compile-thisproject

I can do this with multiple mvn commands, but Can I do this in single maven command.
