Color Help

Curious about the colors of #2 and #3. All 5 are siblings. Dam is a Blue (aaB_C_ddEe), and sire is Fawn (AabbC_ddee).
.
No idea if dam carries b... The black kit in the bottom corner is NOT related, but added to show relative difference to #1s color.
.
Wondering if #2 is lilac and #3 is either blue tort or lilac tort or something else. I am assuming #1 is Blue and #4 and #5 are fawn, although there colors are slightly different. Thanks

3 looks like a fawn to me. Looks like it has agouti markings so it can't be a tort. Just happens to have more coloring & smut than the other two. 2 looks like it might be lilac... if not it could be a very dark blue tort.
