All these three contact types don´t allow sliding between the master and slave bodies, right? Then how can i select the correct one to my simulation? What is the difference between them?
Please, take a look at this post about OptiStruct NL analysis.
There is a topic commenting on these options. (independently of using SimLab or any ohter)

I'm assuming you are using OptiStruct as the solver in SimLab. In OptiStruct, Freeze and Tie contacts work the same way, enforces zero relative motion on the contact surfaces. Typically, they are used to tied parts/components with dissimilar mesh together.
The stick contact enforced contact interfaces not enter the sliding phase. It should only be used on contacts that are closed. It will have some relative motion on contact surfaces in the contact normal direction depending on the stiffness user choose to use, and small to no relative motion in contact transverse direction.
Whether which is the correct one to use, depending on what simulation you are trying to do.
