Help w/signatures on 2 portrait? character? paintings of 2 different old men

I found these at a thrift store yesterday- along with a watercolor by listed artist Larry Greer - I really liked the one of the old man with the umbrella & the cigarette but when I asked the manager how much & he said $100 for all 3 I went ahead and bought the 3 (after looking up the sold prices on Larry Greer I knew it was worth the $100 by itself so if either of the other 2 are by a known artist than that would just be the icing on the cake).
The Larry Greer one was easy - it had a label on the back with the artist & painting info! - but the 2 portraits (these are portraits, right?) have signatures that I cannot decipher!
Does anyone recognize either artist's name? (I apologize for umbrella man's signature photos; it was so dark that these were the best I could get that I thought someone could read)
Thank you for any help with these - as always!

 

Here is the Larry Greer that I also got with the 2 above - pretty nice for a watercolor, right?
Thanks again for any info on the signatures!

 

Wow your Larry Greer sure looks like Will Geer doesn't it!

 

Well, the Larry Greer is gorgeous, but you are much braver than I to pay that for it.
It appears your middle portrait, perhaps done in Asia, is a factory type of painting, perhaps painted by only one person. Your first portrait appears to be a souvie from somewhere. Just my gut take on these 3.

 

Thanks - I feel like I've seen Asian man painting before
