What I am trying to do is to:

Answer 1

I'd refactor a bit:

#!/usr/bin/expect

set timeout 20
set user test
set password test

proc check_host {hostname} {
    global user passwordt

    spawn ssh $user@$hostname
    expect "password"
    send "$password\r"
    expect "% "                ;# adjust to suit the prompt accordingly
    send "some command\r"
    expect "% "                ;# adjust to suit the prompt accordingly
    send "exit\r"
    expect eof
}

set fp [open commands.txt r]
while {[gets $fp line] != -1} {
    check_host $line
}
close $fp
