Your first iRule is the 

HTTP::header
command think you need to include the key word 
value
in 14.

when HTTP_REQUEST {

     Rewrite the User-Agent header value if it's empty
    if {([string length [HTTP::header value "User-Agent"]] == 0) || !([HTTP::header exists "User-Agent"])}{
         Replace the User-Agent header with a default value
        HTTP::header replace "User-Agent" "Mozilla/4.0 (compatible; No User Agent Provided)"
    }
}

With your second iRule looks ok other than the formatting and the perfect use case for using 

switch
, give the following a try and see if this fixes the errors:

when HTTP_REQUEST {
    if {([HTTP::uri] eq "/portal/") || ([HTTP::uri] eq "/")} {
        switch -glob [HTTP::host] {
            "URL*" {HTTP::redirect "http://www.URL.org/contact-us/contact-us.aspx"}
            "path1*" {HTTP::redirect "http://www.anotherURL.com/applications/path1/contact-us.aspx"}
            "path2*" {HTTP::redirect "http://www.anotherURL.com/applications/path2/contact-us.aspx"}
            "path3*" {HTTP::redirect "http://www.anotherURL.com/applications/path3/contact-us.aspx"}
            "path*" {HTTP::redirect "http://www.anotherURL.com/Contact-Us/Contact-Us.aspx"}
        }
    }
}
