The name in lines 4, 11, 26, and 42 is "Clemens" (in the old German handwriting, an "e" looks very similar to an "n", and you have to count all the downstrokes to see that the nine downstrokes in the middle of the name resolve to "emen"; the character looking like a bracket at the beginning of the word is a "C").
The name in line 20 I read as "Hansiosepf" - the first part, "Hans", is a common German short form for "Johannes" (like Bill for William), and I believe you can recognize the "iosepf" as "Joseph". The first letter "H" is differentiated from the first letter "C" in "Clemens" by the left-curling stroke below the line of writing).
The other forenames in lines 18-23 I read as: 18 Valetin (missing the n after the e), 19 Annumaryij (this is a name I am not familiar with, but occurs repeatedly on this page - apparently some form of Anna Maria), 20 Hansiosepf, 21 Luvisa, 22 Katrin, 23 Annij
Edited to correct reading of line 19
