Noticed 1 & 7 both started to ooze a tiny amount of clear sap from the aeroles. Is this normal?

Thanks! (cactus newbie)

(EDITED to add names added in replies below)

#5 Mammilaria gracilis
#7 Ferocactus latispinus

[majcka]

#1 some Ferocactus
#2 some Aloe
#3 Opuntia microdasys alba
#4 Opuntia microdasys
#5 Have no idea
#6 Notocactus uebelmannianus (I think)
#7 Echinocactus texensis (or as one says Homalocephala texensis)
#8 Mammillaria elongata
#9 No clue
#10 Myrtillocactus geometrizans
#11 some Mammillaria
#12 some Mammillaria
#13 Cylindropuntia imbricata ?
#14 Stenocereus pruinosus
#15 Haageocereus maybe????

[Alber khan]

1.F.herrarae
2.Aloe sp
3.Opuntia microdasys
4.Opuntia microdasys
5.M.gracilis
7.Ferocactus latispinus
8.M.elongata (centrals?)
10.M.geometrizans
11.M.hahniana or hageena
14.Stenocereus pruinosus

The white sap which oozes out of the areoles are because of the extra floral nectaries,it is completely normal for ferns and other cacti,unless it is not cleaned by ants,it will get moldy.

...unless it is not cleaned by ants,it will get moldy.

As my office (hopefully) doesn't have ants, do I clean it by myself (Q-Tip or toothpick?) or will the moldy sap eventually just go away. Is the moldy sap harmful?
Thanks!

[haroldo]

One more, if I may...Thanks!

Some type of monstrose Cereus, maybe peruvianus or jamacuru.

8 is Mammillaria elongata (not Myrtillocactus as in the text below the picture).
11: Alber khan meant Mammillaria hahniana or Mammillaria haageana. (But personally I think it looks more like a Rebutia.)

Now that you've said this,I too now think that it is a Rebutia
