Try using just your middle finger for the Em7.
Now, add your ring finger to play the Em chord.
Next, add your index finger (1st fret) to play the E (major) chord.
For the next one (Am), move all of your fingers down a string.
To form an A, place your little finger onto the 2nd fret (B string).
Now remove your little finger and replace your index finger onto the 1st fret.
Now, take your ring finger off the G string (2nd fret) and place it onto the 3rd fret, A string, to form a C.
And, finally, put your index finger on the 2nd fret (A string), your middle finger on the 3rd fret (low E/1st string), and your ring finger on the 3rd fret (hi E/6th string).
Hope that helps you (and doesn't confuse you too much). :)
