The 2nd one is a FN 925 acp probably)? and a guess is worth $175-$250, the 1st one is a DWM, I can look it up, but they are not that common...
The first one is an exact copy of the 1910 Belgian Browning, probably made in the 1920's, it is 32 ACP (7.65mm). I am unsure of the value, but this one looks like it is in excellent condition. Please convince her to sell it to me
