Kaffir lime pests and diseases

Lime, sour    Philippines

Hi I have a kaffir lime tree on a pot. Lately its been having distorted leaves this means i have pest problem is it an aphid ?
the black spots on back of the leaves is the cotton aphids?
( i took out most of these black spots and honeydews)
And my yellowing leaves i have been spraying magnesium solution from epsom salt
Or does anyone know if its instead because of the aphids?
( we had some construction done n I couldn't attend to the garden until now)
And last noticed leaves with hole marks too, another insect?
I also got a kaffir spider from the kaffir ? Is this also harmful to the plant?
Lastly theres another small brown insect on the leaf can anyone pls identify? It flies when you try to catch it and if its harmful to the plant?
pls help thank you very much for any insights on what to do next.

I painstakingly sprayed water and removed all honeydews checked each leaf as best I could. Bonus caught a few flying tiny insects probably the males ones and the cottony eggs it was moving inside. Tomorrow doin the soap w water solution n clean ups on top soil and its surroundings. Thank you very much for all the help.

Hi Bernadette,
The yellowing and the leaves' deformation are caused by nutrients deficiency. Provide citrus fertilizer to your kafir lime. The black insects on the back of the leaves are not aphids but mealy bugs. Collect and destroy the infected leaves and spray soap-based pesticides to prevent mealybugs and other pests. Get rid of the spider because the webs will disturb the plant. The green insect is a mantis and could contribute to protect your plant since it is eating other insects that could be bad for your plant.
