Hai,arnprasad i viewed your photos.The leaves turning yellow in beans is due to magnesium nutrients deficiency. Did the rigid&squash getting full sunlight?Rigid&squash must need high nitrogen in the initial stage.Curling&holes is due to N deficiency.The yellow tiny bugs is aphids in squash&rigid.Another thing your pot size is small for beans,squash,rigid,B gourds.My advice is 1st give full sunlight.Apply panchagavya 2%solution to the above in 10 days interval.Spray neem+punga ennai at5 ml+5ml to 1 litre of water twice a week.

Follow raghu's advice and things should look better.
Few more observations from the pics.
Pic1 - Black Aphids
Pic2 - Lady bug (Beneficial)
Pic4 - There are lots of sucking pests. If you remove them it should be proper. It also looks like leaf curl.
Pic11 - Leaf miner. Pick the eggs of moths found underneath the leafs. Leaf miners are larvae that feed leaf surfaces. Use neem +honge(punga)based pesticide
Pic 12- Watermelon(aphids problem).
Pic13 - Squash - Powdery mildew/sucking pests.
Pic20 - Bean seems to have spider mites issue. Take a close look underneath the leaves. There will be lots of tiny insects with webs
