Gravity, electrical force, magnetic force.
These can act with direct touch.
"False" forces which are dependent on the observer's motion, such as centrifugal force and g forces are also sometimes considered as non-contact
There are also some nuclear forces, but they are not normally observed, and electrical and magnetic forces are really two sides of the same coin.

What is the definition of non-contact forces?
Non-contact forces are forces that can act on an object from a distance without physical contact. These forces include gravitational forces, magnetic forces, and electrostatic forces.
Which forces are non-contact forces?
Non-contact forces include gravitational force, electromagnetic force, and nuclear force. These forces do not require direct physical contact between objects to interact.
What the different types of contact and non-contact forces?
Contact forces involve direct physical contact between objects, such as friction and normal force. Non-contact forces act at a distance without physical contact, such as gravity, electrostatic, and magnetic forces.
How are contact forces and non-contact forces alike?
Contact forces and non-contact forces are both types of interactions that can cause an object to accelerate or deform. The main similarity between them is that they both involve a force acting between two objects, but the key difference is that contact forces require physical contact between the objects, while non-contact forces can act at a distance without direct contact.
How will you differentiate contact from non-contact?
Contact forces involve direct physical interaction between objects, such as friction or tension, while non-contact forces act at a distance, such as gravity or magnetic force. Contact forces are mediators introducing reaction force and normal forces, whereas non-contact forces involve no physical touch between objects.
